A bar magnet of magnetic moment `6J.T^(-1)` is aligned at `60^(@)` with a uniform external magnetic field of `0.44T` . Calculate
the torque on the magnet in the final orientation in case (ii).

Text Solution

Verified by Experts

The correct Answer is:
3
Here, `m=6JT^(-1),theta_(1)=60^(@),B=0.44T`
The torque on the magnet in the final orientation in case (ii) , `tau=mBsintheta=mBsin180^(@)=0`
