One of the methods physicists have used to search for magnetic monopoles is to monitor the current produced in a loop of

wire. Draw graphs of current in the loop vs. time for an electrically uncharged magnetic monopole passing through the loop,

and for an electrically uncharged magnetic dipole (such as a neutron) passing through the loop with its north end head-first.

Don't worry too much about the details of the exact moment when the particle goes through the plane of the loop;

concentrate on the times just before and just after this event. Explain the differences in the two graphs.

(A signal corresponding to a magnetic monopole was seen once in such an experiment, but no one has been able to

reproduce this result, and most physicists seem to believe that the supposed event was due to extraneous noise in the system

or other malfunction of the apparatus.)
