Scientists have developed swarms of tiny magnetic robots that work together like ants to achieve Herculean feats, including traversing and picking up objects many times their size. The findings ...
The team found "vortex loop-shaped quasiparticles" existing within the structure, which exist in all magnetic materials regardless of the strength of the magnetic field, and the material's temperature ...
However, stronger, potentially riskier magnets made from neodymium iron boron (Nd 2 Fe 14 B) are becoming more prevalent, due to their small size and low cost. Researchers in Switzerland ...
