If you think the whole world runs on three-phase AC, you should read about the stubborn persistence of two-phase. Posted in Science Tagged ac motor , RMF , rotating magnetic field , tesla , three ...

The magnetic particles are dispersed in a liquid placed in a container housing the chip. The container is surrounded by three electromagnets energized in sequence to produce a rotating magnetic field.

The Wilcox Solar Observatory has been observing the sun's magnetic field since 1975, and its scientists have been converting those numerical measurements into a map that can now be viewed online ...

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 levitat… ...

Large magnetic-field-induced strains1 have been observed in Heusler alloys with a body-centred cubic ordered structure and have been explained by the rearrangement of martensite structural ...

All three major EV motor types use three-phase alternating current to set up a rotating magnetic field (RMF), the frequency and power of which are controlled by the power electronics that respond ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Three-phase AC induction motors are designed to operate on three separate electric currents, ... In an induction motor, the current in the stator windings generates a rotating magnetic field, ...

The changes in the magnetic field interact with Earth’s own magnetic field, which can cause auroras. As for why it takes the sun 11 years to flip its magnetic field, scientists aren’t totally ...

October 29, 2007 . New system would use rotating magnetic field to detect pathogens WEST LAFAYETTE, Ind. - Researchers at Purdue and Duke universities have developed a technique that uses a magnetic ...
