if every physics lesson in middle and high school had this clarity and narrative quality there would be a lot more physics majors in college. really enjoying this.

I really can not emphasize enough how extremely grateful I am that you play absolutely no kind of music what so ever while you are verbally instructing and save it solely for interludes and transitions. I really enjoy the clarity of presentation I can absorb especially with my hearing condition. It is like chocolate for my brain.

Nice! Loading those magnets was definitely a nail-biter! Thanks for mentioning me. I can't wait to see your demos with this setup!

You, sir, are a top notch science communicator- and I don't say that lightly. Can't wait for the next instalment!

Honestly, I think you are the one youtuber that I have ever been this satisfied with in regards to content. Your content is extremely thorough and very very interesting. You go in depth and extrapolate all the variables and interactions. I could not be happier watching your content Sir, thank you for doing what you're doing.

Wow...I'm in awe. So excited to see where this channel is headed, even moreso lately!!! Nice Applied Sci shout-out, too. Didn't know you guys knew each other. A collab would be scary awesome!

Although scary, this certainly looks far better engineered and thought out than when Brainiac75 combined two 1200kg (2650lb) magnets. That or when the Waterjet channel cut a small neodymium magnet in half and the two halves accelerated apart like a bullet. I'm personally looking forward to more of this project.

The thing I've always found most fascinating about magnets is the repelling force you get when you face the same poles of two different magnets towards one another. As a kid I was never happy with just one magnet, I had to have a second one so that I could repel the other. lol, I'd never try and do that with magnets the size of the ones in this video though! 😉👍

Awesome video, your channel and Applied science are 2 of my favorite channels on youtube. Your's are one of the few doing real science and explaining it well

Great video bossman, its not every day that you can find technical thinkers like your self that can mentally see things on a complex and extremely detailed manner that most couldn't even fathom. Awesome videos 👍

Pure joy watching this and I did laugh out loud each time the Mantrap snapped those magnets in place, I feel your fear. Thank you!

Dear fellow, you are truly amazing! Many thanks for your awesome videos. I wish more YT creators would adopt your clear and concise demonstration and narration style.

I just want to say thank you for making these fantastic videos. You are by far the best channel on this platform. You are knowledgeable, thorough, and precise. Can't wait for the next one!

This channel is unbelievable! Thank you for posting the quality videos that you do.

Dude, I've been deriving the EMF equation for ever and you've enlightened me. Correct me if I'm wrong, I'm pretty new at this, but doesn't that configuration resemble an air gap at the moment of flux, even displaying the fringe factor where the fields meet (@ "air gap"). That makes so much sense being the energy is stored is within the gap. So what you seem to have made is a static E core to focus your magnetic field. Nice! I can think of at least 5 applications for that magnetic circuit off the top of my head. Definitely getting a thumbs up and I'm subscribing. Can't wait to see what else you've got going on.

I love watching a dedicated CRAFTSMAN at work, on ANYTHING, but especially so with MAGNETIC DYNAMICS!! Bravo, sir!!!

No flux meter reading for the big guy? Interested to see what you guys do with this thing.

I clicked this at 3 am thinking this would be kind of boring and very complicated. But it was explained super well and definitely interesting.

Oh yes. Magnets of that size can give you a good workout. Nice to see how well-prepared you are (as always...). Otherwise this would have ended disastrous. Looking forward to more videos on this project!

“Get it nice and slimy” *BREATHING INTENSIFIES*

What does the Gauss meter say when inserted into the large assembly? That's what we're all wondering :)

I would imagine that the gap in your array will, over time, attract and accumulate a lot of ferromagnetic "gradoo". Such undesirables as machine filings, ferrous mineral dust, etc. can really distort your field and are very difficult to remove. Have you made provisions to exclude all the extraneous crud that will eventually make the poles fuzz up?

Any luck on finishing this thing? Perhaps I just overlooked it. I'd love to see what it does with sea water running through it.

17:29 Why do I get the impression that he's trying to bolt it down before it becomes sentient and eats every magnet in sight?

Dude, I love your videos. I don't know your background but you're a good teacher. Teaching has to do with being able to explain information in a way that others can understand it and I think you do a really good job with that. Personally I just like all your experiments. I wish I had Surplus time and money that I could invest in just saying what if.

the pucker factor on insertion is off the charts

Thank you sir for educating us on how the concept of magnetic lines being taken into consideration. That representation of magnets behavior based upon the magnetic-lines is very clarifying.

This is both fascinating and terrifying. Those are some serious magnets you are playing with, great stuff.

Love the content that you and other science KZfaqrs are putting out. If you don't mind me asking, what industries did you work in to learn the myriad of things on your channel, or is it mostly self-taught?

Another great video. Please consider linking to your other channel/other videos in this series in the description of your video. Lots of people will click through to your other videos.

I worked in a UK magnet factory for a summer in the late 80s. Neodymium was just coming in. I heard stories of broken fingers assembling filter grids for food processing. One time I was moving a neodymium based magnet around on a pallet truck. When I hoisted the assembly, the truck came with! That was through about an inch of soft pine making up the pallet. I had to jump on it to get it off. It was an interesting summer!

I found myself really drawn to this channel, the more i watched , the more i was pulled in. Like a moth to a flame. The magnitude was over whelming, you now have a new subscriber.

" I need my non-magnetic wood bar"

Love the over kill jig to load the mags, I got a couple 4" X 2" X 1" N52's...terrifying to hold one of them much less get them within a mile of each other :-)

Fascinating, and I finally know why door catch magnets have two steel plates beside them!

This channel is the best science curriculum out there, I'm so glad that you are sharing your work and genius and I can't wait to see where this goes! I have learned so much from watching these videos that I can't stop talking about them with my family! Every time I watch one your videos I change my mind about which project I think is the most exciting but I think this is the most awesome one yet and am eagerly anticipating the next instalment. Keep up the good work!

And years later, nothing came out of it...

"Those are forces!"

Jeeeez Louise! i jumped outta my skin when the first magnet shot in lol

Another topic idea that might be fun to do along these lines is build and demo saturable reactor/magnetic amplifier. I'm thinking about building one to control heat to a boiler of a particular purpose and they actually look quite straightforward. My basic understanding (which could be wrong) is that you wind an inductor in such a way to induce opposing induced fields in the core. When you run an alternating current through it, this essentially shunts the current through the conductor. However, if you induce a magnetic field in the core to the point of field saturation, there is no longer any induction by the AC line and current is able to flow. Intermediate states of saturation of course allow you to vary the current.

Anyone else have a moment of Bob Ross nostalgia/déjà vu when he started applying the grease.

Where's the follow-up video?

Thank you for displaying the proper amount of caution while handling those magnets. People need to realize that fingers have been totally smashed or severed by magnets this strong. THESE ARE NOT TOYS!!

Well planed assembly and very good explanation (as always). A joy to watch and learn.

Good Work Earthling , You Are Getting Close

This subject has a lot of attraction.

This reminds me so much of my classes in particle accelerator physics. It is awesome to see the practice next to the theory! This is an amazing channel

Those magnets are no joke...when I was a teenager, I used to tear down old IBM server drives with 12" - 14" platters in them and they had massive neo magnets in them...surprised I didn't lose a couple of fingers...lol

Why not to call video: Magnetohydrodynamics -part 2: strong magnets? It would be easy to find all videos from one series.

So how and when can I signup for the Tech Ingredients graduate school?? This is seriously so interesting

You loading those magnets reminded me of separating a stack of 2 inch neodymium discs. Nothing compared to what you were handling, but quite eerie and enough to cut my finger. Scary stuff to work with. Great videos.

I have always been infatuated with magnets especially electromagnetic superinduction. There is so much you can do with magnets. High impulse gravitational wave generators have really caught my latest interest! Really looking forward to you finished project.

so where can I find the follow up video where you use that magnet apparatus?

A nice and classy intro, I like it!

Just found your channel and it’s great, a lot of good info, very impressive, keep up the good work 👍👍👍

I have been working with and studying wind generators and such , this seems to have helped answer some questions and clearified some answers I have had . And of course many more to come

You had me at "Railgun project"...

Where's that follow up video? It's been over a year!

And here i was getting twitchy around my tiny neodymium magnets snapping together.

This channel is amazing. It's like being in a lab with you and doing some real science, many thanks for sharing.

It's been one year since this video and I can't find any followup?

"The forces here can break fingers" except it's more like exploding your hand as if it were a tomato.

I'm glad people mess about and share interesting facts, science and entertainment rather than watching mind numbing TV. Thanks man.

Question!? Is there a formula for finding the proper spacing between magnets? Making a spacer.

Ooops, i need glasses !! Thought the title said " Extreme Midgets " lmao !!

My butt is puckered up soo tight right now. Geesh those magnets are thoroughly terrifying and awe inspiring.

I love that natural way you explain without reading from a teleprompter like in a conversation over a coffee...you are a natural...I bet 1. You are a Physicist, maybe an Engineer 2. You were a teacher.

I agree with a previous poster. You are a very good speaker. No hubris or hubbub. Love the science!

FIRST! As is stated in half the comments in every one of your videos: This is by far one of the most informative, substance packed, and serious channels in youtube. You'll get a lot of subscribers in time. Preferably soon.

"Good thing I greased it!"...I've been there brother.

as always, your explanations are second to none. thank you so much for providing such outstanding content!

Nice work - I've had some very close calls with neodymium magnets - powerful stuff

Speaking of powerful magnetic fields, I don't suppose you can get your hands on some Rebco superconductors, can you?

Did he just say rail gun project?!

I learn something new every episode. Usually many new things. Thanks as always. Great work.

Subbed - I can't help but respect someone who plays with magnets that strong for applications that cool and most importantly has that much careful safety planning! Good job keeping all your digits!

End of the tip where the balls are. Hehe.

Magnets, man, How do they work?

Awesome! Very enlightening, thought out, and explained so even a child can grasp the theory behind this important project ...Thank you

I wonder, is there a relationship between how you extend the magnetic field with a steel rod and how a radio antenna works?

That was amazing. I dare someone to thumbs down this video. We will find you and tickle you without mercy until you retract you're wicked deed. Cheers :)

It's been almost a year and no follow up :(

man why is this channel so underrated?? this is one of the best channels on the interweb

I smiled when I saw that arm-tuck near the end. That's the hallmark of experience.

Homeboy needs to moisturize.

I'm so jealous of this guy's life... all I've ever wanted in life was to invent and play with science!

It's really interesting that the magnets stick more to the steel than to eachother. I would have expected the bottom and top magnets to clamp together even with that plexiglass space

Love the tip, balls, rod, and gap talk.

Wait, after all this, did he never do anything with it? It’s been almost a year.

Camera work is nauseating.

That's intense :D. Can't wait for part 3 :D

another great vid... brilliant explanations as per usual!

Can we get your Son to work on his camera skills, a little too rapid with the movements for the camera and the audience. Steady cam is called 'steady' for a reason, the free camera skills here are all over the place. It is better to use a tripod almost always. Out of focus when transitioning quickly, it's jarring and induces motion sickness. Better you have the second/third camera as has been in the past. Previous camera work was better. It doesn't have to be perfect, though you really got to be conservative in your movement unless cutting to another camera. Outstanding information as always however.

Cameraman, you're doing a terrible job. Stop zooming needlessly and consider using a tripod so you don't have to adjust focus every few seconds. You can always come back later and zoom in using software. In this case, less is more!

God I am just DELIGHTED that this level of content is still available out here.

The things I would do to spend a day with you in your shop.... this is fantastic please always continue making videos

Excellent video! I can't imagine how scary it will be to eventually disassemble this magnetic assembly.

5:56 "...constructing a little magnetic yoke." No, thanks. I don't want all my eggs pointing north! [groans]

This is great stuff! I love your channel. You need more subs for sure. That magnetic field must be huge inside of there!

Everytime one of those magnets snapped into the next position it made me jump. Awesome video and explanation, thank you!
