My rational mind knows it wouldn't work, but it's hard to avoid thinking, "Yeah but if you positioned the magnets *just* right" 😆

The biggest problem the makers of perpetual motion machines have is where to hide the battery

This was SUUPPER interesting , i really thought we could do something like that with magnets but NOW i understand why no one has ever done it , also your explanation is very simple

A defining moment in my youth was when the law of conservation of energy was explained in high school. It fascinated me then and still does. It is one of the certainties in life. People try to prove it wrong again and again, but in the end they always fail. It is brilliantly explained in this video. Science teachers rule!

I notice that he's science explanation so simple and easy to follow

Freeeeee Enerrrrrgy! Great video James. Loved this explanation.

Syphoning someone's petrol and putting it in your car is free energy, so is stealing AA batteries from a supermarket.

I've had arguments with people who thought they had an idea for perpetual motion. It's always some variation of this, and I never convince them they are wrong. I have never found a good method of explaining it in a way that makes sense to them. I think it is because many people get thrown off by the rectangular shape of the magnets, and have a hard time seeing the force as circular. You can't "point" the forces in the way that they imagine.

I like to think of myself as a pretty curious guy, I try to learn everything I can, but every video on this channel has taught something *completely* new to me.

I learned most of this stuff back in high school physics, but it is always nice to be reminded of those fun days!!

The Action Lab: *tries 5 balls on the pendulum* 5th ball: "heheh. I'm in danger."

This channel never stops presenting such interesting topics that we don't normally think about.

When the balls roll together they have additional friction on one another from spinning in opposite directions at the point of contact.

i saw your boyle's flask video and wondered what would happen if you use ferrofluid with a magnet on top of the tube , or at the side of the tube where the ferrofluid falls out . Would be interesting if you could try that

Absolutely mind blowing! Thank you for all you do.

Alongside the cool content and a fun and informing way of presenting it, this channel has by far the best background music, engaging, serious and original. It's not dumbing down.

Brings back memories😌, I used to do this with ball-bearings in a lid along with a small neodymium magnet in the middle

i notice the friction of the two rubbing slows them down as where they touch one is rolling upward and the one touching it is rolling downward stopping the motion , if the moving part was not touching it might move longer

You keep surprising me with your experiments. thanks 🙏

Well done. It’s super interesting learning about the free energy ideas and why they don’t work.

Really Impressive as Always 😍🔥💙❤

Nice! I wish you went into a little more depth into how the extra momentum collisions worked though. I guess the ball on the far end had less magnetic force holding it in, which is why it was able to launch off so fast.

Good to hear this explanation.

thank you sir for bringing up new lessons.

The ball flung-out off the track at 02:12 gets its initial energy from the incoming ball ("trigger") being accelerated by the magnet. However, to do it again and again you must make the effort to pull the trigger ball and then return the "cannonball" to the rear-end of the "cannon". So the same energy you "gain" from the trigger ball is the energy you have to "return" or give back when you pull the trigger away from the magnet and return the cannonball in place. If a perpetual motion machine works, then it is fake.

It would be interesting to see more than two of those first magnetic accelerators in a row. Let's say 10 or 20!

This was very interesting. Thanks!

Very interesting! Thank you.

I suppose that depends on one's definition of "free energy". Solar power is "free", once you've built the device to harness it.

3:27 the second hit makes a spark

Explained really well.

Thanks man your science content is one of the few legit content out there

Magnetic force is essentially a conservative force. Meaning that if the ball moves around a path and arrives back at the starting point, then the net work done is zero. It's worth noting that the shape of the path doesn't matter. If the ball ever returns to the same point (which it does after one circuit) then no work is done. This means no matter how complicated you try and make your SMOT loop if it ever returns to the same point it can't do work. For the same reason attempts to use magnetic shields to make a perpetual motion machine are also doomed to fail. This is similar to gravity. Let's say you set off from your hotel to climb a mountain. It doesnt matter which route you take to get to the top, your change in PE depends only on the height gained between the hotel and mountain top. In addition when you return to your hotel your change in PE is zero. Conservative forces en.m.wikipedia.org/wiki/Conservative_force

We have a new Railgun here

You are incredible goog, love your work.

Great video as always man 🤟🏼

The unparallel magnets result isn't as impressive as the magnetic ball thing, which I felt wasn't explained fully well. But it suggests you could use a whole bunch of them to put a ball bearing through a concrete wall.

Oh no, he's showing people how to make a really deadly rail gun

Wow, this is amazing and fascinating! 👍🏼😀

Great video Loved this explanation 👍👍👍👍

A little more explanation of the balls rolling on the track with one magnet would be helpful. I have a degree in electrical engineering (altho it's been a LONG time since I graduated, with honor btw) and I'm a bit fuzzy on how one ball, being a magnet, causes the acceleration. This was VERY interesting but a little more explanation is necessary.

"Energy can neither be created nor be destroyed".

Good to see someone pushing back against all this overture silliness :)

बहुत अच्छी तरह से समझाया आपने , धन्यवाद।

Any comment on how this could be used with sensors and electromagnets? It seems like a pull-push configuration could be used for magnetic accelerators. I’m sure someone has come up with something better though.

There is free energy in the accelerating expansion of space-time. Extracting it just is not very practical, to say the least :P. Reason: energy conservation is a consequence of time reversal symmetry of law of physics, but dark energy, i.e. presence of non-zero cosmological constant, violates this symmetry. However, cosmological constant affects only very large-scale structures, hence energy is still conserved locally.

I want to see more about this in your future videos.

Question. With your magnet ball setup, if you had a vertical ramp on the other side, or enough of a ramp to have the the high momentum ball to return, will the original ball also shoot off with extra momentum on return? I assume you'd need another ball between the magnet?

If we found a way for perpetual motion, interstellar movement would be petty in comparison.

When YT started, I was always tearing “over unity free energy” videos apart! It was such great fun at first! But after a while it got really boring….the stupidity or downright fakery of those people just wasn’t worth my time and effort to debunk.

Also in Newton's cradle each ball has its own pivot point 1 ball radius apart, so at the point of impact the moving ball is at bottom dead centre. Rolling balls on the curve track, the center of the rolling ball is still 1 ball diameter away from bottom dead center. So that's in addition to the rotation momentum.

I have seen some magnetic toys that seem to spin etc for ever seen a couple last a half hour to 45 minutes on the gentlest of movements. The top thing i think you did a video of one of them.

Instead of "falling" you could use a "downhill", that way you lose a lot less energy, turning the fall into rolling momentum

If you make the "shooting magnents" to go in a circle, will they go forever, or at least a for a while?

I recently made an "Over Unity" device on accident which took me days to figure out WTF was going on. The experiment worked on Resonance and part of the system was a relatively big steel ball and a bench covered with a large metal plate. There is more to it but those are what I think were important to the effect. There are some rods with mass on them which could be tuned. The whole thing can be made to tune itself by resonating the system and the weights "fall" into the Nodes in the standing waves formed in the rods. Once "Tuned" after being bolted to the work bench even the slightest ( and I mean SLIGHTEST ) tap at a very specific spot on the resonance rods, which acted sort of like a tuning fork, caused everything to strongly vibrate for almost a minute at a time all from a split second minor tap. All with a FAR greater Amplitude then the initial tap After much thought trying to figure out what the hell was going on I measured the frequencies the system was vibrating at and turns out it was vibrating at the Frequency of the Electric lines around the area. A frequency that is almost always ringing at all times everywhere and unless you are deep in the woods there is a 60hz noise all over the place as well as its harmonics. The pulsating Magnetic field must be causing the Iron in my system to pulsate with it and the entire system would tune itself to that frequency. The slightest tap seems more like pushing a ball while it was at the top of a hill. Further investigation showed me the system always had a faint, very low frequency pulse to it at all times likely again due to it resonating with the EM field around triggering the most stable subharmonic it could find. Idk, just thought I would share that as I found it interesting because figuring all that took me a good afternoon or two because I for the life of me could not figure out how such long lasting and loud vibrations were coming from this teeny tiny tap at this specific spot, not the spot a mm or two away.... Just THAT spot at the Quarter wave node on the rod. I sat for hours just looking at it confused and gently tapping this one spot expecting it to not to it this time because I felt it should have never been doing it in the first place but it just keep going and going. I would like to harness it somehow but not sure if its possible. I suppose some sort of Radio receiver with a rectifier to split the energy into a Capacitor bank to be measured that was I can 100% prove to myself the EM is what is causing the effect. I am 99.999% positive now but it would be nice to have exact numbers to go by.

That would be cool to see this setup in a ring formation.

Also it should be mentioned that even if you did make a successful loop, magnets lose their magnetism over time anyway so it's still not perpetual.

I swear he could teach college physics

Awesome! Thanks 👏

A likely conversation during dinner at Mr. Science's home: Mrs. Science, "Honey?" Mr. Science, "Yes, Dear?" Mrs. Science, "Why are there dents all over the walls down in the basement?"

Very interesting but is misleading and is lacking clarity. At the end of the first segment, he states that the ball leaving has less total energy than the ball entering. This is demonstrably false. The *total system* has slightly less energy afterward due to friction losses. The gained energy difference between the ball entering and the ball leaving (with both higher kinetic and potential energy) is due to the change in magnetic configuration of the remainig groups of 3 balls... from a higher magnetic potential energy state with the magnet on the end to a lower magnetic potential energy state with the magnet in the center of the groups of three. This can be easily calculated using basic physics principles.

Get your "here within first minute license" here!

"Except the ones who fake it - then it always works" - excellent remark

I tried to replicate some of these magnetic models and although non of them was overunity its a great way to practice various diy skills. And there are electric coils and generators in different configurations. One interesting experiment is a magnetically assisted pulsed dc transformer which I replicated and to my surprise there was an effect that I still can not explain with 100% confidence. Some ideas in overunity field are brilliant if somebody wants to learn some electronics and electrical or mechanical practicals then this is one of many ways to learn new things (I am not saying overunity is possible here ;).

First

Action Lab is my favorite KZfaq channel of all time!

The moment that he mentioned over unity I was like "what the hell happened to this channel??". Then he concluded that it was fake, so nothing happened to this channel! In this channel we respect the conservation of momentum and the laws of thermodynamics!

Just so you know, if you tried to remove one of the balls from the magnet, it would take the same energy as the difference of energy increase observed for the ball. It is similar to those popsicle stick chain reaction demonstrations.

If you like this, you should watch Wintergatan. The "angle" of the rail affects the amount of friction, due to the ratio of the distance the ball rolls to the diameter of the ball (underrolling).

This potential energy has been stored from the very beginning of the universe, and finally released at the making of this video!

Amazing!

We use this kind of move when we play pool to kind of move the white ball along with the aimed at one.

Amazing magnetics.

3:00 Nice rail gun :)

@The Action Lab Good demonstration appreciate that. So even if we have powerful nyeodinum magnet we cannot increase the kinetic energy of these steel balls?

Interesting, one observation (though not enough to significantly impact any of the results) is there is a difference between the newton's cradle and the track. Each ball has it's own pivot and slightly different arc on the cradle, on the track every ball has the identical pivot/arc. Again, doesn't change the ultimate outcome, but may make a slight difference. Still great video, entertaining as always.

3 rules of thermodynamics: you can't win, you can't break even, you can't escape the game

That was super cool

My dumb ass heard him say there's no free energy and immediately responded with " Gibbs would like a word with you !"

Science Class : ''i sleep'' Action Lab : "real shet"

Can you do a science item behind the Searl Effect Generator?

I dropped out in 8th grade and decided to read read read to teach myself. These videos let me know I'm doing a good job of teaching myself

Nice video, good explanation! Was thinking what would happen if you hang one magnet ball on pendulum, will it push last ball around?

Must use this tech setup , in ion thruster ion engine

Awesome !

What if you make electromagnetic smot where you are able to shut off the mag field before the ball reaches the point that is it re-attracted. Then activate the next smot? It seems like a familiar invention...

That was a very fun show.

2:27 If you had another steel ball before the magnet here (so one steel ball before and two after the magnet) would it still work?

This blew my mind

"...except for the ones that fake it. Then, it always works." 🔥🔥🔥

There is always an energy loss between two or more balls rolling together, even if only during the time of impact. They have their surfaces moving against each other with a sliding contact of counter rotation to each other. This loss is much greater compared to the rolling ball's stationary motion between the ball surface and the track. (But the rolling ball sees that resistant frictional force all along its travel path. The pendulum balls do not.) This is why the balls in ball bearings are caged to keep them from rolling (counter- rotationally) against each other. You are not quite correct when the two balls impact on the track, and then the initial ball starts moving again. Though no impact perfectly transfers all inertia, (we will assume it is nearly perfect here) with the target ball at the lowest part of the track, the second ball is still slighty higher on the curve of the track after the impact. Once free to move after the impact, the now stationary ball will want to roll that bit further to the lowest point of the tract. The pendulum balls on the other hand are hanging dead vertical (on nearly frictionless pivots, with the hangers during their impact, all being precisely spaced 1 ball diameter apart) so they have no residual potential (elevational) energy after impact. The hanging balls are also not rotating at all relative to each other, and are only moving linear to each other at impact so they are just very efficient energy wise. The pendulum balls only have to overcome air resistance during their swings and a very small loss due to the impact deformation. The rolling balls have increased air resistance, (due to the additional surface speed of the ball in the air) added friction of rolling on the track, friction between relative motion at the impact sites, the additional rotational inertia starting and stopping the roll, as well as the impact deformation itself. Anyway, I do enjoy your clips.

magnetic shielding is the key for this to workk. u simply use shielding material to counter or nulled certain magnetic space.to prevent pulling force when its not needed..

Ok first off: AMAZING video! I enjoyed it & found it very interesting!(Also, please do remember that I'm not a professional or expert in any field, but rather just another viewer.) I do have a question also: What if you were to arrange the SMOT into a circle, as he discussed, but then have another upside down. Resulting in(theoretically), the ball to float instead of rolling for less friction. Furthermore, if the magnets were "turned off" at the right times for the magnetic forces to pull on the ball, but also not after it has passed them; Would it possibly, have those same forces to both NOT to slow the ball down, & to then have them turn on if it's near the front, to pull on it? I apologize if it's confusing, I tried my best to word it in a comprehensible manner.

make the loop but at the end (where you need to get back up) do the magnet bead in the middle trick seen at 3:00. won't it last longer then or am i mistaken?

He is a pure man of science! Students all over the world should have to listen him.

What would happen if you put two together in a straight line? Adding a straight track separating the two smot magnets in a slight decline to the second set of smot magnets pulling the ball up a short hill as shown in the video?

The earliest I've been. Thanks yt.

Really cool

An invisible force that can „magically“ accelerate things - it sure is tempting to think there is an untapped power source in that. Nice explanation in the video 👍🏻

I agree , some do forget to account for the initial energy of picking up the object... Which is the same point I make when I argue against people that start off a claim for gravity by asking "what caused the apple to fall?" I'm always had to point out , to no avail that the tree raised it up and the weight of the Apple over came the pull of it's branch stem😒
