A square coil is shown above. There is a current flowing in the coil which creates a magnetic moment i. The external magnetic field B is going to the right as shown. The coil starts in the position on the left and then rotates to the position shown on the right. The square coil has sides that are 0.250 m long. The coil has 313 turns of wire. The magnetic field has a magnitude of 66.0 T. The torque created is clockwise and has a magnitude of 1.679 x 104 m N. What is the magnitude of the current in the coil and as we look at the side of the coil facing us in the left picture, is the current going to the right or to the left?
