Consider the loop of wire in Figure 29.25a. Imagine it is pivoted along side O, which is parallel to the z axis and fastened so that side O remains fixed and the rest of the loop hangs vertically in the gravitational field of the Earth but can rotate around side O (Fig. 29.25b). The mass of the loop is 50.0 g, and the sides are of lengths a = 0.200 m and b = 0.100 m. The loop carries a current of 3.50 A and is immersed in a vertical uniform magnetic field of magnitude 0.010 0 T in the positive y direction (Fig. 29.25c). What angle does the plane of the loop make with the vertical?

Consider the loop of wire in Figure 29.25a. Imagine it is pivoted along side 0, which is parallel to the z axis and fastened so that side O remains fixed and the rest of the loop hangs vertically in the gravitational field of the Earth but can rotate around side O (Fig. 29.25b). The mass of the loop is 50.0 g, and the sides are of lengths a = 0.200 m and b = 0.100 m. The loop carries a current of 3.50 A and is immersed in a vertical uniform magnetic field of magnitude 0.010 0 T in the positive y direction (Fig. 29.25c). What angle does the plane of the loop make with the vertical? The loop hangs vertically and is pivoted so that it can rotate around side 4). The magnetic torque causes the loop to rotate in a clockwise direction around side 4, whereas the gravitational torque is in the opposite direction.
