A magnetic monopole is a hypothetical particle with only one magnetic pole. Their magnetic fields would not be divergence-less. Predicted by certain modern theories, including string theory, supergravity, and various popular grand unified theories.

Why don't magnetic monopoles exist?
I think that John Rennie's is a good answer, specially due to the link given where it is shown the reasons why physicists expect the magnetic monopoles to exist. However I would like to stress that th …

Magnetic monopoles gauge theories
1) Universal covering groups are groups with the property of being simply connected. Each algebra has a unique covering group. The other groups, $\{G\}$, associated to the same algebra can be obtaine …

Question from Terning's book
Because the static solution considered is the 't Hooft and Polyakov monopole. There is no (non-Abelian) electric field in this case. A more general solution would be a dyon and then the electric field …

Symmetry in electricity and magnetism due to magnetic monopoles
You actually noticed something that is called electromagnetic duality. A duality correspond to two different theories which give the same physical results as long as we make specific mappings among th …
