Hi, I was wondering whether a bar magnet would induce a current if it was moving external to the solenoid, rather than within the coil. I see no reason why it wouldn't occur, but I've never seen it displayed or mentioned so I'm not sure. Thank you.

Can you explain this a little more in depth? My teacher explained this very superficially so I'm not too sure on this.

Ok, so the title was pretty vague, I'm not sure how to succinctly describe the confusion. Anyway, so I've learned that the power lost is P=I2R, and so by increasing the voltage, as P=VI and is constant, the current will be lowered, and thus the power lost will decrease. I'm confused about a...

Basically I'm not sure how the interaction between the circular magnetic field produced by the current in the wire and the magnetic field of the permanent magnet interact to cause the wire to move in circular motion. If someone could explain that I would appreciate it.

Yep, that makes sense. So just to confirm, is my guess at the end of my post correct? I think I understand the very basic math behind it, and can see how that would result in the three dimensional wave diagram that all the pictures show, so I'm basically content with where I am at now. Even so...

I'm still in year 11, and so haven't really advanced far enough in math to understand Maxwell's equations. I can see some things I know, but for instance I have no idea what the integral with a circle around it means (though I'd be more than willing for anyone to explain the meaning or link any...

- What exactly is the equilibrium of the waves that is shown on graphs? My understanding is that the oscillations are in the strengths of the field, and different sides of the equilibrium represent different directions of the fields. However, I feel as though this contradicts itself in some...

Thanks, I'm not too far in calculus, I've done some differential stuff (recently completed minima and maxima) and a little bit of integration.Thanks for all of the resources though!

I keep seeing that "An atomic orbital is a mathematical function that describes the wave-like behaviour of either one electron or a pair of electrons in an atom" or something similar. However I can't find what the mathematical function is. Can someone tell me or link me to it please?

I know that quarks can never exist in isolation, and also group up so that they have a net neutral colour charge. But I am wondering at the start of the universe, or under very, very extreme conditions (such as the start of the universe) would quarks have been able to exist by themselves. I have...

Well my guesses for using the planets instead of the sun would be: When we are exploring the solar system, we care about the position of the planets relative to the suns position. When we gravitationally slingshot our spacecraft s, we add the velocity of the planets relative to the sun to the...

Thanks a lot for that, I was trying to google it but I guess "flinging" isn't specific enough haha. Thanks.

So I've heard things like the sun (or I guess any star" would be able to "fling" objects away from the solar system, I have no idea how this would work. Would this be similar to quasars, how the black hole "flings" matter away that reaches the escape velocity?
