A 25 cm long solenoid has radius 2 cm and 500 total number of turns. It carries a current of 15 A. If it is equivalent to a magnet of the same size and magnetization `vecM` (magnetic moment/volume), then `|vecM|` is:

A

`3piAm^(-1)`

B

`30000Am^(-1)`

C

`300Am^(-1)`

D

`3000Am^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
`M` (mag, moment/volume) `=`
`(NiA)/(Al)`
`=(Ni)/l`
`=((500)50)/(2xx10^(-2))`
`=30000Am^(-1)`
