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.

Magnetism is a natural force, one that works at a distance. Magnets get their force from magnetic fields created by the atoms within the metal. Magnets are useful for things like turbines we use to ...

"As the magma cooled to form what is today the world's solid outer crust, magnetism was locked into minerals containing iron, such as magnetite." When you purchase through links on our site, we may ...

Earth's invisible magnetic field acts as a vital shield, protecting life from dangerous cosmic radiation and solar particles.

Researchers used hundreds of thousands of computer simulations to examine the remnants of these ancient magnetic fields, which still reside within the "cosmic web" billions of years later. Magnetism ...

Bloch oscillations are periodic oscillations of quantum particles in a repeating energy "landscape" (e.g., a crystal lattice) ...

Magnetic separation has become increasingly popular in biomedical science and industry. This technology uses magnetic properties of micro/nano-sized particles to separate macromolecules of interest, ...
