Question:
A magnetically "hard" material is in the shape of a right circular cylinder of length L and radius a. The cylinder has a permanent magnetization M0, uniform through-out its volume and parallel to its axis.
(a) Determine the magnetic field H and magnetic induction В at all points on the axis of the cylinder, both inside and outside.
(b) Plot the ratios B/μ0M0 and H/M0 on the axis as functions of z for L/a = 5.
