Question

A circular loop of wire of radius 11.5 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 0.460 T/s in some time interval, what is the magnitude of the emf induced in the loop during this interval?
mV

A circular loop of wire of radius 11.5 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 0.460 T/s in some time interval, what is the magnitude of the emf induced in the loop during this interval?

Explanation / Answer

Required magnitude of emf in mV = 1000*pi*(0.115^2)*0.460 = 19.10 (mV)
