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 ...

WEST LAFAYETTE, Ind. - Researchers at Purdue and Duke universities have developed a technique that uses a magnetic field to selectively separate tiny magnetic particles, representing a highly ...
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 ...
A magnetic field is the magnetic influence of electric currents and magnetic materials. The magnetic field at any given point is specified by both a direction and a magnitude (or strength); as such it ...
