Answer to Question #339256 in Electricity and Magnetism for Miller

Question

A circular loop of wire of radius 0.25 cm is expected to an external

magnetic field that is perpendicular to the plane of the loop. For a time,

the magnetic field decreases at a rate of 0.0035 T/s. What is the

magnitude of the induced electromagnetic force in the loop?

Answer 1

$F=qvB=2\pi qr\dot B=8.8\cdot 10^{-24}~N.$
