A short bar magnet placed with its axis ...

A short bar magnet placed with its axis at `30^(@)` with an external field of 800 G experiences a torque of 0.016 Nm.
The bar magnet is replaced by a solenoid of cross sectional area `2 xx 10^(-4) m^2` and 1000 turns, but of the same magnetic moment. Determine the current flowing through the solenoid.
