Each of the 10 turns of wire in a vertical, rectangular loop carries a current of 0.22 A. The loop has a height of 8.0 cm and a width of 15 cm. A horizontal magnetic field of magnitude 0.050 T is oriented at an angle of u = 65° relative to the normal to the plane of the loop, as indicated in FIGURE 22-48. Find

(a) The magnetic force on each side of the loop,

(b) The net magnetic force on the loop,

(c) The magnetic torque on the loop.

(d) If the loop can rotate about a vertical axis with only a small amount of friction, will it end up with an orientation given by θ = 0, θ = 90°, or θ = 180°? Explain.
