Both scenarios are same.

There once was a man called Don Who was ever so easy to con He made a great hash Of physics' worst trash And all that he said was wrong.

Depending on the observer's motion, it could be a sum of both magnetism and the electric force that explains the total force on the charged particle.

This must be where ICP gets their name. :V

It's pretty wild that the generation of magnetic fields by currents is an everyday relativistic phenomena (tiny charge density imbalance), and ferromagnetism is an everyday quantum phenomenon (tiny atomic current loops).

The relativistic effects being so tiny and the strength of electromagnetic effects in lab frame or charged particle frame of reference is simply a testimony to the strength of electromagnetism and the very large number of particles involved in a length of wire. Gravity by contrast is orders of magnitude much weaker.

Electric forces are really strong compared to gravity, so it's not at all surprising that low speeds are already have tremendous effects.

if you’re capable of thought, this is a terrible piece.

And here I was, thinking it was really about trains, because of all the train examples and whatnot...

@@danieloberhofer9035 Die Arbeit heißt im Original "Zur Elektrodynamik bewegter Körper" und erschien in den "Annalen der Physik" 1905. In dieser Arbeit leitet Albert Einstein die Gleichungen der Speziellen Relativitätstheorie her: "Man denke z. B. an die elektrodynamische Wechselwirkung zwischen einem Magneten und einem Leiter. Das beobachtbare Phanomen hängt hier nur ab von der Relativbewegung von Leiter und Magnet, während nach der üblichen Auffassung die beiden Fälle, daß der eine oder der andere dieser Körper der bewegte sei, streng voneinander zu trennen sind." (Womit auch klar ist, wo der Begriff Relativitätstheorie ursprünglich herkommt.)

@@danieloberhofer9035 Actually Einstein didn't invent it, he just used the work of myriads other scientists before him. Which is why none of the special relativity concepts bear his name other than "Einstein's special relativity theory", which is but a summary of everything other scientist already found. His genius was making sense of all the things other geniuses found 💁‍♂

​@@Ebani Lol. The same can be said of every scientists. It isn't for no reason that Newton wrote "If I have seen further it is by standing on the shoulders of Giants". Note that even that metaphor is way older than Newton.

@@estranhokonsta newton said the standing on giants thing in response to someone who was very small, implying he would not contribute at all.

what about the random root square speed? and also how about the fact that electrons are Bloch waves inside?

@@mrtienphysics666 It does get fun really quickly!

Well, let's modulate those with laser and we'll obtain some FOCK photon states

I wish he would quantify the cause and the effect, wish he'd show the math I'm sure it's not too hard.

It's more complicated than the video here, but it's the same thing. For like poles, the electric field is similar to like charges, while for opposite poles, the contraction is more like concentrating opposite charges. It's >>much

I also would like to see if relativistic effects can explain the permanent magnets. Permanent magnets attract or repel each other without presence of moving charges, right?

@@stefanyankov3801 No. Remember that electrons both move and spin within atoms.

Wouldn't an EM wave be the exact same phenomena just oscillating? Instead of charge moving uniformly in one direction, it changes direction. Acceleration is required to create electromagnetic waves and the change in direction is the acceleration. We describe the oscillation by its relationship to time as frequency and its relationship to the speed of light by wavelength.

You have to derive a 4-vector field. In that case, relativistic effects looks like a 4-rotation of the vectors.

Hey what about stationary permanent magnets, how can they be explained with the wire theory?

My question as well.

Quick hopefully useful rake: If two charges are moving past you at some speed relative to your rest frame then they are in a different frame - one moving at their speed relative to you. >Everything< in that reference frame looks shortened in that direction to you including the space between the particles. Think of them as ticks on a ruler. The ruler shrinks so the ticks look closer together to you. The fact that there is no material ruler there, doesn't mean there isn't the "frame ruler".

On top of that, the length contraction does not depend on the direction of current flow. The effect should be the same in either direction. Switching the charges you look at when you "change" current flow direction does not make physical sense.

It’s everything!

Light is both

What’s not wild at all is that you put that exact same comment, word for word on more than one video. Doug, it got old before you even did it, time dilation in reverse!

As a former ICP fan, I had to defend that constantly.

@@mountfairweathersearch for insane clown posse and magnets

Haha, the lyrics had nothing to do with the complexity of the subject and how many people get it wrong. It was about mystifying the topic and science denial. Just read the very next lines of the song.* They absolutely deserved every bit of the mockery they got. *Violent J rolled back the 'liars' claim made in those lyrics and said it was more about scientific explanations destroying the wonder of things, which personally I think is also daft and wrong, but then how would he know? Hes never actually listened to any of them...

@@xtieburn I don't claim to have any insight into what these literal clowns were thinking, and I frankly don't care. What I do know is that the memes overwhelmingly focussed on that one specific part of the lyrics and did not include the lines that followed. I also know that tons of people felt prompted to provide explanations that overwhelmingly did not rise above middle school level physics. My point is simply that that even among people who have reached what would be considered a respectable level of education, the percentage of people who can properly explain how magnets work is vanishingly small.

A good reason for that is as I have understod it Albert Einstein wasn't all that good at mathematics. He had a very good mind to find new ideas. This is why I can't understand that todays Physicians demand that an idea is calculated through before they even want to consider it.

You forget that according to Einstein there is no gravitadional pull of the earth. It is space time that is bend. Personally I am yet to be convinced that the Physicians current explanation is correct. In my oppinion it is only one way of looking at it.

That is fantastic! I never quite could visualize how it would look when moving towards a current.

@@narfwhals7843 thanks narf. I recognize you from some other comment sections btw.

@@imaginingPhysics 👋 I hope that's a good thing. I immediately recommended your video to someone in another comment :)

@@narfwhals7843 very much in a good way sir. Till our commentworldlines cross again.

The confusion doesn't only arise when we mix SR with pre SR electromagnetism. The confusion arises from the lack of reference frame in Maxwell's Equations. The confusion is what _leads_ to Special Relativity. Read Einstein's original paper "on the electrodynamics of moving bodies". It is not too difficult.

For current to flow the wire needs to form a loop. On the return leg the spacing of the opposite charge is contracted.

I watched a S. A. Video where Nick Lucid explained the same as this video, but I think he put a squirrel there to be the observer for the different reference frames you have there.

It is my understanding that if you extend the same logic to two differently moving observers, they will not agree on the measurable electric/magnetic ratios of the same objects measured. But they can agree on the same universal outcomes of those differing measurements to a very high degree of accuracy by using Einstein's equations.

Nice but false

Exactly. try to lorentz contract a point charge…

Time dilation. When you see two parallel charges move you calculate the force between them with their charges. You observe that they don't accelerate that strongly and call that a opposing magnetic force. When you consider Relativity you find that the amount by which they accelerate too slowly is exactly the slowing of time you observe due to their motion. The critical speed where these effects cancel is the speed of light, which they can not reach.

No it does not represent real motion. But it means you can _think_ about it as if it did, as long as you're careful. But it does represent real angular momentum. And the magnetic field is related to momentum in space.

The sign of the charge just determines the direction of the force.

@@narfwhals7843 my question was not "Does magnetic force work between charges of opposite sign?", but: when considering the magnetic interaction between just two electrons, is it necessary to introduce an additional proton for magnetic force to exist, as it is done in the video?
