cture 14- cture 14- 1 Magnetic Monopoles How can you isolate this magnetic charge? Try cutting a bar magnet in half. In fact no attempt has been successful in finding magnetic monopoles in nature. Does there exist magnetic charge , just like electric charge? An entity which carried such magnetic charge would be called a magnetic monopole (having + or - magnetic charge).

cture 14- 3 Magnetic Force on a Current Consider a current-carrying wire in the presence of a magnetic field B . There will be a force on each of the charges moving in the wire. What will be the total force dF on a length dl of the wire? Suppose current is made up of n charges/volume each carrying charge q < 0 and moving with velocity v through a wire of cross-section A . A
