Question: Assume that A = 50 2 a z Wb/m in a certain region of free space. (a) Find H and B. (b) Find J. (c)

Assume that A = 50ρ2az Wb/m in a certain region of free space.

(a) Find H and B.

(b) Find J.

(c) Use J to find the total current crossing the surface 0 ≤ ρ ≤ 1, 0 ≤ ϕ < 2π, z = 0.

(d) Use the value of Hϕ at ρ = 1 to calculate H · dL for ρ = 1, z = 0.
