Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

The design of a bipolar single-turn coil made of a YBCO bulk was proposed by the group of electrical application of superconductors, at the University of Extremadura, to be an element for the design ...

A rotating unidirectional magnetic field generated by a motor-mounted permanent magnet was used to dynamically aggregate paramagnetic particles from suspension to form chains. Video microscopy and ...

The article presents a comparison between the figure of Galileo Ferraris and Nikola Tesla that are worldwide considered the fathers of the rotating magnetic field and the induction motor. The ...

The windings are conductive wires through which the electric current flows. The stator, which contains a set of windings, generates a rotating magnetic field thanks to an alternating current. The ...

Just like a permanent-magnet motor, the energized windings create an electromagnetic field that interacts with the stator's rotating magnetic field, spinning the rotor.

The magnetic field lines, showing the direction of force, were undetectable before now. The map is a first step toward understanding how magnetism can shape the universe. Out There.

To make an electric transformer, copper wire is often wound around a magnetic metal like iron, a setup that helps concentrate a magnetic field. (Image credit: FactoryTh via Getty Images) ...

An asynchronous or induction motor's rotor rotates at a somewhat slower speed than the stator field. The stator's magnetic field is therefore changing or rotating relative to the rotor. The AC ...
