A thin torus, of radius 0.1 m, is wound uniformly with 100 turns of wire. If a current of 2.0 A flows through the wire, what are the magnitudes of the B and H fields generated within the torus if it contains (i) a vacuum and (ii) a material with relative permeability 500? What is the magnetization in the material (Fig. 13.13)?

Solution:
A thin torus, of radius 0.1 m, is wound uniformly with 100 turns of wire. If a c
