Multiple Choice

A closed flat loop conductor with radius $2.0 \mathrm {~m}$ is located in a changing uniform magnetic field.If the emf induced in the loop is $2.0 \mathrm {~V}$ what is the rate at which the magnitude of the $\vec { B }$ field is changing if the $\vec { B }$ field vector is oriented perpendicular to the plane in which the loop lies?

A) 0.16 T/s
B) 1.0 T/s
C) 0.080 T/s
D) 2.0 T/s
