Scientists suspect that a rapidly spinning, highly magnetic neutron star, or "pulsar," dwells at the heart of the Milky Way.

The Brunhes-Matuyama reversal, which happened around 775,000 years ago, backs up the new findings. A study from 2019 found that the flip took 22,000 years to complete – so drawn-out reversals may be ...

Earth’s magnetic poles have flipped many times before, and a future reversal could weaken radiation protection, disrupt navigation, and reshape life over thousands of years. Probe finds Air India ...

Abstract: To tackle the torque pulsation challenge in permanent magnet machines (PMMs), this article proposes two design methods that involve shifting the permanent magnet pole pairs. Method 1 ...

Abstract: Accurate calculation of air-gap magnetic field distribution in permanent magnet machine (PMSM) constitutes a critical foundation for the design and optimization of electromagnetic ...
