(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A disc of conductivity σ is in an axial magnetic field B = B_{0}cosωt

The disc has radius a and thickness s

2. Relevant equations

possibly dP/dv =JE(dot product of two vectors) but I have absolutely no clue if it is relevant or not.

I think J=σEmight be relevant, but I have no idea.

3. The attempt at a solution

I really don't know where to begin with this. I know that P= I V but I am completely lost as to whether or not I am supposed to derive the potential difference from the magnetic field, or what. This should be a simple plug- and - chug problem, but I can't seem to figure out where to begin, and I am feeling stupid because this is the first one in the problem set. Am I supposed to derive the electric field from the B field?
