Magnetic Force Does NOT Exist!

We've all played with magnets before watching them attract or repel via magnetic force. In this video, I make the bold claim that magnetic force doesn't actually exist. It's an illusion.

Actually there is a barber shop in Austin called Shear Madness.

Absolutely correct. While special relativity forced us to change much of our views of physics, Maxwell's equations needed no change whatsoever. They were already relativisticly correct. What I tell my students is that magnetism is merely the relativistic correction of the electric force.

[joshwilliams]

As a plasma physicist I was ready to rage on here, but as it turns out you're dead on the money - electric and magnetic forces are coupled. Hence what appears to be an electric force in one frame of reference may manifest as a magnetic force in another frame of reference.

This channel takes the difficult and makes it "fun and easy' to understand. Nick is a genius and makes science easier to understand. Don't get me wrong, I only understand a portion of this stuff, but it's a lot more than I get from audiobooks on the same subject. He takes what I thought I knew and presents it in such a way where the loopholes of misunderstanding are plugged up. I'm glad there is so much I don't know, now I have a reason to learn it in a new light. Nick makes it fun. He's funny, entertaining, and an excellent professor. I must assume he has a Phd in physics. Yes? No?

[seankelly]

Wow, I’m both confused and enlightened simultaneously. My brain hurts but I like it.

[Anghelnicolae]

Man, you can take any subject on the planet and make it interesting. That's a gift.

[Badgerheist]

I've been searching for a video like this for a couple years now. You nailed it! Thanks for presenting it in such an accessible format.

[GordyDhatt]

I totally love how -- whether it was deliberately or inadvertently -- you managed to insert the Wilhelm Scream (TWICE -- 0:30 & 3:00)!!

You're one of my absolute favorites!

[ecapers]

I still don't really get magnetism. Everywhere I look for an explanation seems to define magnetism in terms of itself. And why do they say that electric and magnetic waves are perpendicular to each other if they're actually one in the same? I'm sorry for not getting this well, but I have such a hard time visualizing what's responsible for what, and how.

[mathmachine]

0:29 you're right. I'm gonna open up a hair salon and call it

[mumtaz]

"it's okay to be a little crazy"
I liked that one

[biswanathdutta]

This channel ought to have millions of views!

[rapture]

As a carpenter who is trying to learn about electronics and forces, I have to say, I think that you nailed it. We need these types of videos for everyone to think on. Thanks buddy....

[stormk]

This might be the first channel I support via patreon just because the content is so good and yet the subsciber count seems low.

I never thought of the impact of length contraction on the observation of charge neutrality of a live wire. Interestingly, the length contraction argument applies in the wire rest frame as well. It must be that the electrons in the current naturally space space themselves out in a way that exactly compensates for the length contraction an observer in the wire's rest frame would measure in order to preserve charge neutrality in the wire rest frame. Thus, only in the rest frame of the wire (or in an inertial frame moving perpendicularly to the wire) does the wire appear to be charge neutral. In any other inertial frame, the length contractions of the wire and the electron current would be different. This would result in observations of non-neutral linear charge densities... Cool stuff! Thanks for sharing!

I like your approach to the unification of forces... then defining forces... then defining the entities that define forces (and the forces we are based upon, where we can call something 'alive' or 'evolving' in a defined forward time).

[croakmcgloak]

When i came in this video i thought this guy was gonna be all kinda crazy. But when he explained himself i knew where he was coming from, nice vid!

[rinwesley]

Oh for Pete's sakes. I Can't believe it has taken so many years for someone to finally explain how electromagnetism works. I've been confused for so long. This video has made a sub out of me.

[randyrobinson]

This is the best science channel of all time, hands down. Discovery's got nothin' on you.

[aquastudio]

Great video! Didn't know about special relativity until now but I don't think I am at that level of physics so this is a good reference video for my future physics studies. Keep rolling!
