Physicists in Europe and the US have developed a new technique for reversing the "core polarization" of the tiny magnetic whirlpools that exist in certain materials. The reversal, which can be ...

Researchers have created an optical device that can generate both electric and magnetic vortex-ring-like light patterns.

Vortex is ubiquitous in nature including spiral arms of galaxy, planet rotation, hurricane (tornado). A vortex is a typical and well-known magnetic domain structure in dimensionally confined ...

Magnets often harbour hidden beauty. Take a simple fridge magnet: Somewhat counterintuitively, it is 'sticky' on one side but not the other. The secret lies in the way the magnetisation is arranged in ...
