Chapter 28, Problem Q28.1DQ

A topic of current interest in physics research is the search (thus far unsuccessful) for an isolated magnetic pole, or magnetic monopole. If such an entity were found, how could it be recognized? What would its properties be?

To determine

Recognition magnetic pole or magnetic monopole.

Explanation of Solution

Magnetic flux through a closed surface will be proportionate to the total number of magnetic monopoles in the volume enclosed by the surface.

When the net magnetic flux links with an arbitrary surface area which is enclosed by a quantity is not zero. This quantity indicates a magnetic monopole.

Monopole will be analogous to a point charge and its magnetic field would terminate on it.

Magnetic monopole properties:

• From image force magnetic monopole which can trapped in material of ferromagnetic by a value $\text{10e}\text{V}/\stackrel{\text{ο}}{\text{A}}$.
• Through superconducting ring if a pole travels, then there should be magnetic flux change through the ring which is independent of velocity.
• The magnetic monopole spin will be $1/2$ or $0$.
• The magnetic pole interaction of magnetic charge with magnetic nuclear dipole may cause formation of M-nucleus bound system.
• The bound states of monopole nucleus may exist only with large gyromagnetic nuclei ratios.

Conclusion:

Thus, the signification of magnetic monopole and properties are determined.
