A rectangular loop of wire of dimensions 12 cm × 25 cm faces a long straight wire. The two long sides of the loop are parallel to the wire, and the two short sides are perpendicular; the midpoint of the wire is 8.0 cm from the wire. Currents of 95 A and 77 A ?ow in the straight wire and the loop respectively.
(a) What translational force does the straight wire exert on the loop?
(b) What tourque about an axis parallel to the straight wire and pass through the center of the loop does the straight wire exert on the loop?
