Q. A magnet is brought towards a coil (i) speedly (ii) slowly, then the induced e.m.f/induced charge will be respectively
A) More in first case/More in first case
B) More in first case/Equal in both cases
C) Less in first case/More in second case
D) Less in first case/Equal in both cases
Explanation
(b) The magnitude of induced e.m.f. is directly proportional to the rate of change of magnetic flux. Induced charge doesn’t depend upon time
