Matching particles and antiparticles are small units of matter that have the same mass but opposite electric charges. Typically, these units of matter with opposite electric charge tend to annihilate one another.
When researchers use an optical Kerr microscope to zoom in on thin films of magnetic material, given the right conditions, they observe a sort of micro-scale magnetic hurricane. Physicists call these whirlwind-like magnetic ...
