A closely wound solenoid of 800 turns and area of cross section `2*5xx10^-4m^2` carries a current of `3*0A`. Explain the sense in which the solenoid acts like a bar magnet. What is its associated magnetic moment?

A

`6JT^(-1)`

B

`0.9JT^(-1)`

C

`JT^(-1)`

D

`0.6 JT^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
D
Given, number of turns , n=800

Area of cross-section of solenoid , `A=2.5 xx 10^(-4)m^2`
Current throug solenoid , l=3A
Using the formula of magnetic moment
`M=n/A=800 xx 3 xx 2.5 xx 10^(-4)`
`M=0.6JT^(-1)` along the axis of the solenoid
