Question: The free space region defined by 1 < z < 4 cm and 2 < < 3 cm is a toroid of rectangular cross

The free space region defined by 1 < z < 4 cm and 2 < ρ < 3 cm is a toroid of rectangular cross section. Let the surface at ρ = 3 cm carry a surface current K = 2a_z kA/m.

(a) Specify the current densities on the surfaces at ρ = 2 cm, z = 1 cm, and z = 4 cm.

(b) Find H everywhere.
