Question:

The cones Î¸ = 21—¦ and Î¸ = 159—¦ are conducting surfaces and carry total currents of 40 A, as shown in Figure 8.17. The currents return on a spherical conducting surface of 0.25 m radius.

21° r= 0.25 m 40 A // 40 A 40 A 40 A 40 A, 40 A

(a) Find H in the region 0 < r < 0.25, 21—¦ < Î¸ < 159—¦, 0 < Ï• < 2Ï€.

(b) How much energy is stored in this region?
