The torque on the magnet in the final orientation

Explanation

Torpue ` =| oversetto m xx oversetto B | = mB sin theta `
For `= 180^(@) , ` we have
Torpue `= 6xx 0.44 sin 180^(@) =0`
[If the student straight away writes that the torque is zero since magnetic moment and magnetic field are anti parallel in this orientation , award full mark
