A magnet is brought towards a coil (i) speedily (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

Text Solution

Verified by Experts

The correct Answer is:
B

The magnitude of induced emf is directly proportional to the rate of change os magnetic flux. Also, induced charge is `dq=-(dphi)/(R)`, which is independent of time.
