Question 1

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
