Thank you! I like this explanation, and I accept Gauss law always holds, but...how can we do the same with a similar Gaussian surface for the infinite plane? I understand that it may be more complicated because of "mathematical infinities"...but there's got to be a way!
Also, by "force" I meant...
Whoops! I'll just delete the old thread...next time I'll wait for the moderators. I'll copy my response from there to here and message a moderator to delete it (it doesn't let me delete it for some reason...sorry, I'm not very familiar with PhysicsForums).
Thank you kuruman...I'm a little...
Thanks for reading. I originally asked this question on Stack-Exchange, but I haven't received any satisfying answers yet.
The only answer I've received (as of posting this) uses the "method of images" concept...but, in the book where I got this example from (Purcell) the author hints that the...
If you've learned about relativity, its allways cool to look at these problems relativistically, which is where magnetic fields emerge from anyways.
If the current between 2 wires next to each other is moving in opposite directions (so the electrons are moving in opposite directions), electrons...
Hey @helios1234 , for every electron that enters the capacitor plate connected to the negative terminal of the battery, one electron leaves the positive side of the battery, so they end up having equal charge.
As for why that happens: you've probably heard an electric field is constant across a...
@Mentz114
1. Are magnetic fields made up of photons?
2. Nvmind
3. Right, but what does it mean by frequency? Whats a higher energy photon?
4. What is the difference between an electromagnetic field and an electromagnetic wave...? (Wave as in visible light or UV...etc)
Hey, @Mentz114 thanks so much for your answer. So I've got a couple questions:
1. So if for example, I've got current flowing past in a wire and thus have created a magnetic field around that wire, would that magnetic field would be somehow completely different from the "light quanta" that are...
So I'm kind of confused. The way I understand it, an electromagnetic field is just a regular electric field viewed from a relativistic point of view, meaning that since we see the charges moving relative to us, we feel like the particles and the fields created by them come closer together (I...
