Some magnets can be turned on and off. There are two kinds of magnets: temporary and permanent. Find out the difference and why discovering how to turn a magnet on and off changed our world.

A researcher in New Jersey says he had a nuclear fusion breakthrough while helping his son with a science project. He realized he could explore which kinds of permanent magnets could be powerful and ...

Physicists Prof. Dr. Ingo Rehberg from the University of Bayreuth and Dr. Peter Blümler from Johannes Gutenberg University Mainz have developed and experimentally validated an innovative approach for ...

As we’ve noted, rare earth materials aren’t particularly rare—they’re relatively abundant, but they’re highly dispersed, meaning that large volumes of material must be collected, from which the rare ...

Magnetic levitation systems harness the unique properties of high-temperature superconductors and permanent magnets to achieve frictionless, contactless motion. The core principle underpinning these ...

General Electric Co.’s laboratories in Schenectady last week demonstrated (see cut, p. 23) a tiny magnet, about the size of a pellet of buckshot, holding aloft a five pound flatiron. The magnet weighs ...

China’s exports of permanent magnets rose to a six-month high in July, marking a second month of growth after the government pledged to accelerate export permit approvals for the rare earth derivative ...
