Problem
Exactly half of a rectangular conducting loop lies in a uniform magnetic field perpendicular to the plane of the loop. At some point in time, the magnitude of the magnetic field starts rapidly decreasing. While this is happening, which of the following statements most accurately describes the effect on the loop?
(a) The loop is pulled into the magnetic field;
(b) the loop is pushed out of the magnetic field;
(c) the loop starts rotating;
(d) the behaviour of the loop cannot be determined unless the direction of the magnetic field is completely specified.
