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 Ampère's circuital law to find H and B within the conductor
(c) Show that V x H = J within the conductor
(d) Find H and B outside the conductor.
(e) Show that V x H = J outside the conductor
