Problem
A rectangular coil ABCD is placed with its plane vertical between the poles of a magnet so that the magnetic field is directed from the north pole on the left to the south pole on the right. At an instant, current flows upward through side AB and downward through side CD. Using Fleming’s left-hand rule, what is the direction of the force on side AB?
(a) Toward the south pole (to the right)
(b) Upward along side AB
(c) Out of the page (toward the observer)
(d) Into the page (away from the observer)
