This video explores why Formula 1 has not transitioned to fully electric power, focusing on technical, regulatory, and performance considerations. It highlights factors such as energy density, race ...

Abstract: The flux density waveform in the air gap of a surface-mounted permanent magnet motor demonstrates key design information such as the back electromotive force, cogging torque and torque ...

With their sleek lines, smoking tyres and thunderous engines, Formula 1 cars have been the fastest road vehicles for the past 50 years. But electric vehicles may soon become the quickest on Earth, as ...

There are precision measurements, and then there’s the Laser Interferometer Gravitational-Wave Observatory. In each of LIGO’s twin gravitational wave detectors (one in Hanford, Washington, and the ...

Decades ago, the entrance to the somewhat sleepy Francis Bitter National Magnet Lab at MIT was decorated with a movie poster from The Magnetic Monster, a 1953 American science fiction film. Since then ...

The density of an object is the object’s mass divided by its volume. The density is characteristic of the material that the object is made of, and its value can help to identify the material. Except ...
