APFIVE Lenz's Law and Magnetic Force
A circular loop of wire with radius 0.1 m lies in the xy-plane in a uniform magnetic field of 0.5 T directed along the positive z-axis. If the magnetic field suddenly begins decreasing at a rate of 0.2 T/s, what is the direction of the magnetic force on the induced current in the loop?
A
Radially inward toward the center of the loop
B
Clockwise around the loop when viewed from above
C
Counterclockwise around the loop when viewed from above
D
Radially outward from the center of the loop
