This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to audio speakers. Oh, and without it we’d live in eternal darkness.

The electrical manipulation of magnetism and magnetic properties has been achieved across a number of different material systems. For example, applying an electric field to a ferromagnetic material ...

Scientists have managed to use electrical fields to control the magnetic oscillations of certain ferrous materials. This has opened up huge potential for computer technology applications, as data is ...

MIT researchers have now replaced silicon with a magnetic semiconductor, creating a magnetic transistor that could enable ...

Rare earth magnets, critical to modern technologies, remain dominated by China despite Western efforts to diversify supply, with Europe increasing imports and the U.S. falling behind.

WRITTEN in colloquial language, this book, which is a first-year course on magnetism and electricity, will appeal to many beginners besides the students in technical institutions, for whom it is ...

It is anticipated that within just a few decades, the surging volume of digital data will constitute one of the world's ...

A simple one-step process recovers more than 90% of rare earth elements (REEs) from magnets ( Proc. Natl. Acad. Sci. U.S.A. 2025, DOI: 10.1073/pnas.2507819122).

Magnetism is due to the magnetic fields around magnets. The fields can be investigated by looking at the effects of the forces they exert on other magnets and magnetic materials. Electrical quantities ...
