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 ...

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 ...

DC machines can be classified as self-excited, separately excited, permanent magnet (PM), and brushless. Self-excited machines can be further classified as shunt, series, and compound. Compound ...

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 ...

Using new numerical simulations and observations, scientists may now be able to explain why the Sun’s magnetic field reverses every eleven years. Using new numerical simulations and observations, ...
