Say I have a single turn of a coil in an external magnetic field. How do I calculate the voltage induced in this turn ? Initially I would use Faraday's law

∇E = -j ω B

But what should I use for B ? Will B not be a combination of both the external field as well as the field created by the current induced in the coil:

∇B = μ J = μ σ E


Suddenly the problem seems more complicated!
