A spherical conducting shell is placed in a time-varying magnetic field. Is there an
induced current along the equator?

I'm thinking there should definitely be some kind of net charge movement throughout the shell, but I don't know if I can apply Ampere's Law in this circumstance. I'd like to draw a loop around the circumference and ignore the fact that the shell's a closed surface, but I don't know if this analysis would be accurate.

I meant Faraday's Law, sorry.

not accrate you haven't considered damping effect
