Find the magnetic field due to a dipole ...

Find the magnetic field due to a dipole of magnetic moment 1.2 `Am^(2)` at a point 1 m away from it and making an angle `60^(@)` with the axis of the dipole.

A

`1.6 xx 10^(-7)T`

B

`1.6 xx 10^(-7)T`

C

`1.6 xx 10^(-7)T`

D

`1.6 xx 10^(-3)T`

Text Solution

Verified by Experts

The correct Answer is:
C
`B=(mu_(0)M)/(4pi r^(3)) sqrt(3 cos^(2)theta +1)=(1.2 xx 10^(-7) xx 4pi)/(4pi xx 1^(3)) sqrt( 3 xx ((1)/(2))^(2) +1) =1.6 xx 10^(-7)T`
