Figure P28.31 shows a rectangular loop of current in an external magnetic field. Initially the plane of the loop makes a \(65^{\circ}\) angle with the magnetic field.

(a) Determine the direction of the magnetic force exerted on each side of the loop. Treat side 4 as though it were one unbroken wire.

(b) Determine the direction of the torque on the loop about the axis shown as a dashed line.

(c) What is the orientation of the loop once the system reaches equilibrium?
