Question

A circular coil of radius 10.5 cm is located in a region of magnetic field where

B(t) = (+0.2 T/s)t

and with the magnetic field oriented perpendicular to the plane of the loop. Find the magnutide of the induced EMF in this loop at

t = 11.5 s.

Answer 1

Answer #1

B(t) = 0.2 t

dB/dt = 0.2 T/s

so inducede emf = NAdB/dt

emf e = 1 *3.14*0.105 * 0.105 * 0.2

emf e = 6.923 *10^-3 OR 0.006923 Volts
