The magnetic field (B) inside a long solenoid having n turns per unit length and carrying current / when iron core is kept in it is `(mu_o` = permeability of vacuum, `chi` = magnetic susceptibility)

A

`mu_(0)nI(1-chi)`

B

`mu_(0)nIchi`

C

`mu_(0)nI^(2)(1+chi)`

D

`mu_(0)nI(1+chi)`

Text Solution

Verified by Experts

The correct Answer is:
D
`mu=mu_(0)(1+chi)`
`(B)/(H)=mu_(0)(1+chi)`
`B=mu_(0)H(1+chi)`
`B=mu_(0)nI(1+chi)`
