Magnetic Monopoles
Magnetic monopoles are hypothetical particles that possess only one magnetic pole, either a north or a south, unlike conventional magnets that have both. In classical physics, magnetic fields always come in pairs, meaning every north pole is accompanied by a south pole. The existence of magnetic monopoles would challenge this understanding and could provide insights into the fundamental nature of magnetism.
The search for magnetic monopoles has intrigued scientists for decades, including notable physicist Paul Dirac, who proposed their existence in the 1930s. While no experimental evidence has confirmed their presence, discovering magnetic monopoles could have significant implications for theories in particle physics and cosmology.
