Question:
A hollow cylindrical shell of radius a is centered on the z axis and carries a uniform surface current density of Kaaφ.
(a) Show that H is not a function of ϕ or z.
(b) Show that Hϕ and Hρ are everywhere zero.
(c) Show that Hz = 0 for ρ > a.
(d) Show that Hz = Ka for ρ < a.
(e) A second shell, ρ = b, carries a current Kbaϕ. Find H everywhere.
