Abstract: This paper proposes a novel method for calculating winding inductances in electrical machines using mesh-based magnetic equivalent circuit (MEC). In the proposed framework, the inductances ...

Abstract: High permanent magnet losses of high-speed permanent-magnet synchronous motors will lead to irreversible demagnetization of permanent magnet, which has a serious impact on the motor ...

At the National High Magnetic Field Laboratory in New Mexico a pulsed magnet has achieved fields of around 100 tesla, making it the world-record holder for non-destructive magnetic field strength. The ...

In this video, we experiment with a powerful Neodymium N52 magnet sent by a fan. Our experiments include performing a pull-up while suspended by the magnet, extracting iron from cereal, and ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky.

The magnetic field that protects our planet is shifting – and one region is fading fast. Over the South Atlantic, a weak spot in Earth’s magnetic shield has grown steadily since 2014. It now stretches ...

A weak spot in the Earth's magnetic field is growing over the South Atlantic Ocean, according to more than a decade's worth of satellite data collected by scientists. The magnetic field surrounding ...

Inside its boundaries, the magnetic field that radiates away from Earth's interior dips down to an altitude of about 120 miles (200 kilometers) above the planet's surface, which is much lower than the ...

Our objective was to assess the extent of sociodemographic and geographic disparities in the use of community‐based rehabilitation following stroke, an area that has been understudied. We conducted an ...

Richmond parents are speaking out, accusing the West Contra Costa School District of keeping local kids from utilizing a newly-renovated athletic field. They’re also accusing the district of giving a ...

A team of U.S. researchers has pulled off a double win for electric vehicles: making batteries safer and recycling them more effectively. According to a recent article by Interesting Engineering, ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...
