Moving monopoles caught on camera: Researchers make visible movement of monopoles in assembly of nanomagnets

For decades, researchers have been searching for magnetic monopoles -- isolated magnetic charges, which can move around freely in the same way as electrical charges. Magnetic poles normally only occur in pairs. Now a team of researchers has managed to create monopoles in the form of quasiparticles in an assembly of nanoscale magnets and to observe how they move using a microscope at the Swiss Light Source to make the magnetic structures visible.
