Today, materials scientist Peter Mullner answers a child’s question about magnets: ‘What are magnets made of, and how do they ...

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 ...

"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 ...

The magnetic field lines, showing the direction of force, were undetectable before now. The map is a first step toward understanding how magnetism can shape the universe.

Deep in Chile’s Atacama Desert, scientists studied a green crystal called atacamite—and discovered it can cool itself dramatically when placed in a magnetic field. Unlike a regular fridge ...
