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 ...

The joint research team was led by Prof. WANG Hui and Prof. ZHANG Xin from the High Magnetic Field Laboratory, Hefei Institutes of Physical Science. In recent years, magnetic nanoparticles (MNPs) have ...

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 ...

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 ...

It is like jumping on and off a carousel: what happens to neutrons changing from a non-rotating frame of reference into a rotating frame of reference -- and back? 30 years ago, scientists predicted ...

One of the primary ways that gyroscopic motion can be applied is in the monitoring and/or maintaining of the orientation of an object. A broad array of engineering applications are based on gyroscopic ...

A common approach to measuring distance or angle in a rotating system is by using an incremental encoder or resolver. The majority of industrial applications, such as machines or drives, are dominated ...
