A magnet is moving towards a coil along ...

A magnet is moving towards a coil along its axis and the emf induced in the coil is `epsilon` . If the coil also strats moving towards the magnet with the same speed, the induced emf will be

A

`varepsilon//2`

B

`varepsilon`

C

`2varepsilon`

D

`4varepsilon`

Text Solution

Verified by Experts

The correct Answer is:
C
`epsilonpropv` , `epsilon'=2v`
`(epsilon')/(epsilon)=2 implies epsilon'=2epsilon`
