Each of the 10 turns of wire in a vertical, rectangular loop carries a current of 0.22 A. The loop has a height to 8.0 cm, parallel to the y-axis, and a width of 15 cm. A horizontal magnetic field of magnitude 0.050 T is oriented at an angle of θ = 65 ∘ relative to the normal to the plane of the loop, which aligns with the x-axis. a) Find the magnetic moment. b) Find the magnetic torque on the loop. c) 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 deg, θ = 90 deg, or θ = 180 deg? Explain.
