If you made a motor out of a magnet, a wire coil, and some needles, you probably remember that motors and generators depend on a rotating magnetic field. Once you know how it works, the concept is ...

Researchers have found that exposing a certain class of particles -- micron-sized beads endowed with a special magnetic sensitivity -- to a rapidly alternating, rotating magnetic field causes them to ...

Smaller, streamlined electronics make lubricant-free, low-friction magnetic bearings feasible for more rotating machines. • Magnetic bearings support rotating shafts in five axes without solid or ...

No matter how its done, with whatever level of fakery, magnetic levitation just looks cool. We don’t know about you, but merely walking past the tackiest gadget shop, the displays of levitating and ...

Pulsars are rapidly rotating, highly magnetic neutron stars generating radiation through the acceleration of charged particles along their magnetic field lines. The rotation speed limits the extent of ...

Researchers are planning to use magnetic bacteria to fight cancerous tumors. They have now found a way for these microorganisms to effectively cross blood vessel walls and subsequently colonize a ...
