Why Does a Metal Ring Heat Up in a Changing Magnetic Field?

[a1densmom]

If you place a metal ring in a region in where a magnetic field is rapidly alternating, the ring may become hot to your touch. Why?


Is it because a changing magnetic field can create electric fields? I AM SO CONFUSED...and it seems so simple?!?

Well, I wouldn't call it simple.
You have a few more steps to explain why it gets hot.
Any other remarks?

 

[a1densmom]

can you give me a hint?

 

[a1densmom]

What does deflecting mean?

What does deflecing mean?

I don't know, why?
Hint: what will an electric field do inside of the conductor?

I thought that it might have something to do with it... I was lost.

Is it because the voltage is increased? I don't know... I am trying. Thank you for helping me.

A changing magnetic flux, here you can think of it as just a changing magnetic field, induces an emf in the ring. What will happen in the ring with this induced emf acting?
(Faraday's/Lenz's law is a bit confusing) ; )

Okay... I got it, I think... Thank you so much. Sorry if I annoyed you.
