Question

The magnetic field between the Horizontal poles of an electromagnet is uniform at any time,
but its magnitude is increasing at the rate of 0.020 T/s. The area of a horizontal conducting loop
in the magnetic field is 120cm², and the total circuit resistance, including the meter, is 512.
Induced emf and the induced current in the circuit are
a) 0.18 mV, 0.38 MA
b) 0.50 mV, 0.048 mA
C) 0.24 mV, 0.048 mA
d) 0.12 mV, 0.48 mA​

Answer 1

The correct answer si option D

Explanation:

e = Rate of change of magnetic field x area
