Electromagnetic Induction Ques 27
27. The total charge induced in a conducting loop when it is moved in a magnetic field depend on
[1992]
(a) the rate of change of magnetic flux
(b) initial magnetic flux only
(c) the total change in magnetic flux
(d) final magnetic flux only

Answer:
Correct Answer: 27.(c)
Solution:
- (c) $q=\int i d t=\frac{1}{R} \int e d t=\frac{1}{R} \int(\frac{-d \phi}{d t}) d t$
$=\frac{1}{R} \int d \phi \quad$ (taking only magnitude of e $)$
Hence, total charge induced in the conducting loop depends upon the total change in magnetic flux.
