A circular coil 12.0 cm in radius and composed of 145 tightly wound turns carries a current of 2.20 A in the counterclockwise direction, where the plane of the coil makes an angle of 15.0 with the ' A y axis (see figure below). The coil is free to rotate about the z axis and is placed in a region with a uniform magnetic field given by B = 1.20 j T.
