Question

The magnetic flux in a coil of 100 turns increases
by 12 x 103 Maxwell in 0.2 s due to the motion
of a magnet. The emf induced in the coil will be:-
(1) 0.6 mV (2) 0.6 V (3) 6 V (4) 60 V​

Answer 1

Answer:

emf= rate of change of flux × number of turns =

0.2

12×10

3

×10

−8

×100=0.06V
