A rectangular conducting loop of width 0.10 m and length 0.30 m and resistance 2.0 Ω is pulled at constant speed into a uniform magnetic field of magnitude 0.5 T (directed into the page). The loop is initially completely outside the field. Determine the speed \(v\) (in m s\(^{-1}\)) required so that the maximum induced emf in the loop is 0.5 V. Then calculate the induced current, the magnetic force on the side of length 0.30 m that is entering the field at that instant, and the electrical power dissipated in the loop.

Answer Options

A. v = 4.00 m/s, I = 0.30 A, F = 0.045 N, P = 0.150 W
B. v = 3.00 m/s, I = 0.25 A, F = 0.040 N, P = 0.100 W
Correct Answer C. v = 3.33 m/s, I = 0.25 A, F = 0.038 N, P = 0.125 W
D. v = 2.50 m/s, I = 0.20 A, F = 0.030 N, P = 0.080 W
Correct Answer
C
Correct Option:
v = 3.33 m/s, I = 0.25 A, F = 0.038 N, P = 0.125 W
