Two identical, current-carrying rectangular loops are oriented at right angles, one in the vertical x-y plane, one in the horizontal x-z plane. The horizontal loop moves infinitesimally slowly from z = −∞, through z = 0 (where the centers of the two loops coincide), to z = +∞.(a) Graph (qualitatively) the non-zero component of the force exerted on the vertical loop by the horizontal loop as a function of the position of the latter.(b) Repeat part (a) for the torque exerted on the vertical loop by the horizontal loop.
