1.	AB and CD are smooth, parallel, horizontal rails on which a conductor T can slide. A cell, E, drives current i through the rails and T. (a) The current in the rails will set up a magnetic field over T. (b) T will experience a force to the right. (c) T will experience a force to the left.(d) T will not experience any force.
Answer» Correct Answer is: (a, b) Current in AB and CD causes magnetic fields in the same direction on T, upward in this case. Hence there is a net magnetic field over T.
