Magnetic monopoles

Definition

Magnetic monopoles are hypothetical particles that have a single magnetic pole, either north or south, unlike traditional magnets which have both. They are predicted by certain theories in physics but have not been observed experimentally.

5 Must Know Facts For Your Next Test

1. Magnetic monopoles would violate the classical law of magnetism, which states that magnetic poles always come in pairs (north and south).
2. The existence of magnetic monopoles is predicted by grand unified theories and certain extensions of quantum mechanics.
3. If discovered, magnetic monopoles could provide an explanation for the quantization of electric charge.
4. Dirac's theory suggests that the existence of even a single magnetic monopole could explain the discrete nature of electric charge through topological considerations.
5. Despite extensive searches in natural minerals and particle accelerators, no conclusive evidence for magnetic monopoles has been found.
