Question

The total charge induced in a conducting loop, when it is moved in magnetic field depends on

(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 1

Answer is : (c) the total change in magnetic flux

Induced emf is given by

∴ Total charge induced = ∫ idt

Thus, the induced charge in a conducting loop, moving in a magnetic field depends on the total change in magnetic flux.
