The magnetic field inside wires In a regular household wire, current I flows (uniformly!) down a long straight conducting wire of radius R. Assume the metal is a "magnetically linear" material, and find the magnetic field B as a function of distance s from the center of the wire (both inside and outside the wire) What are all the bound currents in this problem?
