Abstract: Direct-drive wave energy converter (DDWEC) is more widely used due to its simple structure and high conversion efficiency. Different kinds of linear machines are used in DDWEC to improve the ...

Abstract: This article presents both analytical calculations and empirical measurements of the magnetic force between the permanent magnet (PM) and rotor yoke in a large-scale PM synchronous generator ...

Satellite data reveal that a weak region in Earth's magnetic field has grown by an area roughly half the size of continental Europe in the last 10 years. A weak region in Earth's magnetic field has ...

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 ...

Magnet makers face longer license reviews, sources say Scrutiny is similar to April, at height of U.S.-China trade war China's rare earth exports dropped 31% in September BEIJING, Oct 14 (Reuters) - ...

A giant dent in Earth's magnetic field is continuing to expand, according to the latest data from a trio of satellites monitoring our world. It's called the South Atlantic Anomaly, stretching across ...

Scientists have discovered that a 'weak spot' in Earth's magnetic field is growing at an alarming rate. Known as the South Atlantic Anomaly (SAA), the region has expanded by an area nearly twice the ...

Last week China introduced new draconian restrictions on rare-earth magnet exports, a reminder of its power to disrupt global supply chains—and cause American manufacturers, including carmakers, to ...

Learn how to make a generator at home using magnet energy with our step-by-step guide! This video will walk you through the process of creating a simple yet effective generator using basic materials ...

Using 11 years of magnetic field measurements from the European Space Agency's Swarm satellite constellation, scientists have discovered that the weak region in Earth's magnetic field over the South ...

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 ...
