For the bearingless permanent magnet synchronous motor (BPMSM), to improve the sinusoidal degree of air-gap magnetic field, and solve the problem of difficulty in solving the air-gap magnetic field, a ...

Beneath the bogs of New Zealand’s Northland is a massive Ngāwhā kauri, living from 41,000 to 42,500 years ago, which gives an isolated, unbroken record of a period when Earth’s magnetic field declined ...

The Solar Orbiter space mission, a joint initiative of the European Space Agency (ESA) and NASA, has for the first time ...

This article proposes an accurate and computationally efficient hybrid analytical (HA) model for the air-gap magnetic field computation of asymmetric-stator-pole flux reversal permanent magnet machine ...

Neanderthals have long been the subject of intense scientific debate. This is largely because we still lack clear answers to ...

Scientists convert Earth's magnetic field collapse from 41,000 years ago into chilling audio, revealing ancient cosmic ...

A rare geological event occurs every 300,000 years or so: the Earth’s magnetic poles flip. The magnetic poles are the two ...

The president's comments came as workers erected two 88-foot-tall flagpoles, one on the North Lawn and one on the South Lawn, at the White House on Wednesday.
