Abstract: | Analytical methods to investigate the interaction of magnetic monopoles with known magnetic media have been developed. Trapping
energies of monopoles inside ferro-magnetic or super onducting materials of size greater than about 10−6 cm are found to be of the order of several kiloelectron volts. These are two to three orders of magnitude higher than in
paramagnetic materials. Thus if stable magnetic monopoles exist at all in the universe, they are perhaps trapped in these
magnetic materials. The effect of the finite size of the magnetic bodies is taken into account explicitly in our calculations
of the trapping energy. |
