It's not surprising that the powertrains of electric cars differ quite a bit from traditional internal-combustion engines. Although they have fewer moving parts, the rare-earth magnets that help power ...

If you took introductory physics, you learned about the “fundamental forces.” It goes something like this: All interactions are the result of one or more of five basic forces: strong nuclear, weak ...

The incredible power of electric motors can only be matched by how difficult it is to make them. These things need magnets to work, and magnets are made from rare earth elements, which are difficult ...

A current carrying conductor creates a magnetic field around it, which can be comprehended by using magnetic lines of force or magnetic field lines. Magnetic field in a current carrying straight ...

Japan’s IHI has announced a “breakthrough” in magnet technology for high-speed motors, which could enhance the performance of future electric aircraft. The company says that it and local collaborators ...

New nitride materials could let electricity control hidden magnetic spin patterns, pointing toward faster and more stable ...

I have talked about the course I teach for elementary education majors before (videos for education majors, Spring Course reflections). Anyway, the nature of the course is that students collect ...

The rapid increase in electric vehicle adoption in recent years has highlighted a crucial issue: the energy conversion ...

From time to time, the Earth's magnetic poles flip, leaving us without a protective magnetic field for up to centuries ...
