# Experimental Realization of a Dirac Monopole through the Decay of an Isolated Monopole

Magnetic monopoles have been sought for decades but never definitively observed. Recent experiments have created different analogs of monopoles in Bose-Einstein condensates, including quantum-mechanical and Dirac monopoles. Now a new experiment in this system shows how a quantum-mechanical monopole can evolve into a Dirac monopole.
