Monopole
A magnetic monopole is a hypothetical elementary particle that has only a north pole or a south pole.
Explanation
The Maxwell equations describe how electric and magnetic fields are generated by charges, currents and changes of these fields. One of the equations says that magnetic charges do not exist

∇⋅ Divergence B Magnetic induction
This means that magnetic monopoles do not exist.
HistoryAccording to the Dutch physicist Gerard 't Hooft (1946), monopoles are conceivable. |
