Induced Electric Fields | EMI | Physics | Khan Academy

We understand why EMF is introduced when a rod/coil is moving, but we have seen it can also be induced when they are not moving. How do we explain this?

In the first part of ur video, consider we have uniform magnetic field and then move the coil, there will b no current even though electrons are in motion (because we are moving coil, so according to ur explanation there should be some current), there is no current in the coil

Recheck the explanation❤

1) Where does flux for Electric field w/o coil come from? 2) Direct current(dc) induces Magnetic field. Can Magnetic field induce dc.

Everything is very clear thank you a lot. But there is something i don't get it. Why the inducting eletric fiel'ds lines must be closed (cycle)? If i make the math there is no doubt. But i can not understand the reason it has to be like that. Of course we are sure 100% that it happens but i just do not know why. The easy explanation is that it has to be like that because of the Lenz law. But still i do not like it as an anwser. If you could help me with that i would be greatful!

What will decide the location of the centre of these concentric loops?
