A small bar magnet experiences a torque of 0.016Nm0.016\,\text{N\,m} when placed with its axis at 3030^\circ with an external field of 0.04T0.04\,\text{T}. If the bar magnet is replaced by a solenoid of cross-sectional area of 1cm21\,\text{cm}^2 and 10001000 turns but having the same magnetic moment as that of bar magnet, then the current flowing through the solenoid is
