Demonstrates how electricity can be produced from magnets through various experiments. It explains that electric currents can create magnetic effects, forming electromagnets that only work while ...

For about 700 years, magnetism has been known as the force that stands still. Last week a physicist claimed to have proved that magnetism moves. Professor Felix Ehrenhaft, formerly of Vienna, told the ...

Crystal thermal transport in altermagnets. The left part, which includes the balls, arrows, and spin density isosurfaces, represents a typical altermagnet. When a temperature gradient field is applied ...
