and it may soon be possible to build permanent magnets as strong as neodymium magnets, but without any rare earth metals. In fact, the only thing needed to make them is iron and nitrogen ...

Magnet Expert Ltd filmed two super strong magnets crashing into each other at 200 mph. They recorded the video after YouTube users commented asking to see the result of two strong magnets ...

While scientists have toyed with the idea of using AF-MPD thrusters since the 1970s, the Paihau-Robinson team believes it could b ...

One tool in particular, a toolmaker’s magnet, always came in handy. These are strong magnets that have been ground flat, square, and parallel. He really only needed one magnet, so he started to ...

Old TVs and computer monitors used cathode-ray tubes (CRTs), and they relied on electron beams guided by magnetic fields to create images. So, a strong magnet nearby could throw those beams off ...

but it lacked a sufficient coercivity — a measure of a magnet’s resistance to other strong magnetic fields,” explains Sagawa. “However, I knew that if we could produce magnets using ...
