Question:
An annular disk has thickness t, inner radius R1, outer radius R2, and conductivity σ. Let a radial current I0 flow from the inner periphery to the outer periphery of the disk.
(a) If n is the conduction electron density, use Faraday’s law to show that a circular current
flows when a constant magnetic field B is applied perpendicular to the annular plane.
(b) Show that every origin-centered circle in the disk is an equipotential.
