A long, straight, nonmagnetic conductor of 0.2 mm radius carries a uniformly distributed current of 2 A dc. (a) Find J within the conductor.
(b) Use Amp`ere's circuital law to find H and B within the conductor.
(c) Show that ∇ × H = J within the conductor.
(d) Find H and B outside the conductor.
(e) Show that ∇ × H = J outside the conductor.
