1)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 0.00220 m from the center?

2)A 0.150 T magnetic field B crosses the xy plane perpendicular to the x axis and at an angle of 70.0

2)A 0.150 T magnetic field B crosses the xy plane perpendicular to the x axis and at an angle of 70.0

Explanation / Answer

2) Flux through portion in xy-plane:
B A cos? =
(0.150 T)(7.00 m)(7.00 - 1.50 m)cos(90 - 70) =
5.426 T-m
