Induced Current From a Changing Magnetic Field
A rectangular loop with dimensions a × b is situated in the xy-plane. A uniform magnetic field is directed in the positive z-direction, and its magnitude increases at a constant rate dB/dt. Which of the following correctly describes the induced current in the loop?
A
Alternating in direction as B increases
B
Clockwise when viewed from the positive z-axis
C
Zero because the field is perpendicular to the loop
D
Counterclockwise when viewed from the positive z-axis
