a An infinitely long solid conductor of radius a
a An infinitely long solid conductor of radius a
(a) An infinitely long solid conductor of radius a is placed along the z-axis. If the conductor carries current I in the + z direction, show that
within the conductor. Find the corresponding current density,
(b) If I = 3 A and a = 2 cm in part (a), find H at (0, 1 cm, 0) and (0, 4 cm, 0).
