Problem
A rectangular coil ABCD is kept in a vertical plane between the poles of a horseshoe magnet. The uniform magnetic field acts from left to right. A direct current flows upward along side AB and downward along side CD. Which one of the following describes how the two vertical sides will initially move?
(a) AB moves out of the plane of the paper; CD moves into the plane.
(b) Both AB and CD move out of the plane of the paper.
(c) AB moves into the plane of the paper; CD moves out of the plane.
(d) AB moves upward along the coil; CD moves downward along the coil.
