A solid wire with a radius of 3.00 mm carries a current of 0.0530 A. Assume the current is uniformly distributed in the wire.
(a) What is the magnetic field strength at the center of the wire?
(b) What is the magnetic field strength at a distance of 1.00 mm from the center?
(c) What is the magnetic field strength at a distance of 0.00250 m from the center?
