A rectangular coil with 20 windings carries a current of 1.87 mA flowing in the counterclockwise direction. It has two sides that are parallel to the y-axis and have length 8.01 cm and two sides that are parallel to the x-axis and have length 6.15 cm. A uniform magnetic field of 49.5 ?T acts in the positive x-direction. What torque must be applied to the loop to hold it steady?
