An induced emf is produced when a magnet is plunged into a coil. The magnitude of the induced emf is independent of

A

the strength of the magnetic

B

the speed with which the magnetic is moved

C

the resistivity of the wire of the coil

D

the number of turns in the coil

Text Solution

Verified by Experts

The correct Answer is:
C

`phi=N.(mu_(0))/(4pi).(2M)/(x^(3))A`
`N` : Number of turns `e=-(dphi)/(dt)=(mu_(0))/(4pi)(6M)/(x^(2))(dx)/(dt)AN`
`=(mu_(0))/(4pi)(6Mv)/(x^(2))AN`
`epropM` , `epropv` , `epropN`
