A rectangular coil with 20 windings carries a current of 2.0 mA flowing in the counterclockwise direction. This coil has two sides that are parallel to the y-axis and have length 5.0 cm and two sides that are parallel to the x-axis and have length 3.0 cm. A uniform magnetic field of 50 µT acts in the positive x-direction. What torque (in N.m) must be applied to the loop to hold it steady?
