Magnetic Force on a Closed Current Loop
A closed wire loop is composed of a semicircle of radius 10 cm and the straight segment that forms its diameter. The loop carries a 3.0 A current and is placed in a uniform magnetic field of 0.25 T, which is directed perpendicular to the plane of the loop. What is the magnitude of the net magnetic force on the loop?
A
0 N
B
0.24 N
C
0.075 N
D
0.15 N
