Rotating Loop and Graph

APPH12-KSYEE5

A wire loop can rotate between the ends of two permanent magnets as shown in the diagram above. A voltmeter is connected to the ends of the wire loop and some outside force causes the wire loop to rotate at a constant rotational velocity.

Which of the voltage vs. time graphs below best represents the induced emf in the wire loop for one full rotation?

A
B
C
D
