A copper conductor is placed over two stretched copper wires whose ends are connected to a D.C. supply as shown in the diagram.

(a) What should be the magnetic poles at the points A and B lying on either side of the conductor to experience the force in the upward direction?

(b) Name the law used to find these polarities.

(a) The magnetic poles at the points A and B should be of opposite polarity for the conductor to experience the force in the upward direction. So, if point A is North pole then point B should be South pole and vice versa.

(b) Fleming's left hand rule can be used to find these polarities.
