A Closed Loop Conductor That Forms a Circle with a Radius

Multiple Choice

A closed loop conductor that forms a circle with a radius of 2.0 m is located in a uniform but changing magnetic field. If the maximum emf induced in the loop is 5.0 V, what is the maximum rate at which the magnetic field strength is changing if the magnetic field is oriented perpendicular to the plane in which the loop lies?

A) 0.40 T/s
B) 2.5 T/s
C) 0.080 T/s
D) 5.0 T/s
