The intensity of magnetization of a magnet of magnetic dipole moment `1.2 "Am"^(2)` and dimension `0.15 m xx 0.02 m xx 0.01m` is…..... A/m.

A

`4 xx 10^(4) A//m`

B

`2 xx 10^(4) A//m`

C

`10^(4) A//m`

D

`8 xx 10^(4) A//m`

Text Solution

Verified by Experts

The correct Answer is:
A
Intensity of magnetization
`M_1 = ("magnetic dipole moment")/( "volume")`
`= (1.2)/( 0.15 xx 0.02 xx 0.01)`
`= 4 xx 10^(4) A//m`
