We're not going to get into the finer details of Faraday's law of induction, but

to be able to talk a little bit about it,

we need to have some idea of what magnetic flux is.

So if we take some sort of closed loop, and

we make a surface that connects all of the sides of this loop, And

then we count the amount of b fields or the magnetic fields that's

going through this surface and then divide it by the area of this surface,

that gives us magnetic flux which is represented by capital C.

This is somewhat similar to the way that we calculated current.

We calculated the amount of charge that was moving through some surface in time.

So it's a similar kind of idea.
