Exercise 6

A very large slab of material of thickness d lies perpendicularly to a uniform magnetic field of intensity H 0 = a z H 0. Ignoring edge effect, determine the magnetic field intensity in the slab:
a) if the slab material has a permeability , and
b) if the slab is a permanent magnet having a magnetization vector M i = a z M i.
