If the solenoid in the above question is free to turn about the vertical direction, and a uniform horizontal magnetic field of `0*25T` is applied, what is the magnitude of the torque on the solenoid when its axis makes an angle of `30^@` with the direction of the applied field?

Text Solution

Verified by Experts

Here, `M=0*6JT^-1`(from Ques. 5) `B=0*25T`, `tau=?` `theta=30^@`
As, `tau=MB sin theta` `:. tau=0*6xx0*25sin30^@=0*075N.m.`
