A circular loop of wire of radius 12.3 cm is placed in a magnetic field directed

Question

A circular loop of wire of radius 12.3 cm is placed in a magnetic field directed perpendicular to the plane of the loop, as shown in the figure below. If the field decreases at the rate of 0.530 T/s in some time interval, what is the magnitude of the emf induced in the loop during this interval?
mV

Explanation / Answer

mV = 1000*pi*(0.123^2)*0.530 = 25.200 (mV)
