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? (Check yourself by verifying that the total bound current is zero) What can you say about...

An infinitely long, straight, cylindrical wire of radius R carries a uniform current density J. Using symmetry and Ampere's law, find the magnitude and direction of the magnetic field at a point inside the wire. For the purposes of this problem, use a cylindrical coordinate system with the current in the +z-direction, as shown coming out of the screen in the top illustration. The radial r-coordinate of each point is the distance to the central axis of the wire, and...
