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 case
C
Less in first case/More in second case
D
Less in first case/Equal in both case
Answer
More in first case/Equal in both case
Explanation
Solution
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.
