Modern low-power solutions to computer memory rely heavily on the manipulation of the magnetic properties of materials.

Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it ...

That’s the subtle magnetic force — generated by the planet’s molten metal core — that surrounds Earth, not unlike the force around a bar magnet.

As you may recall from Physics 101, a changing magnetic field (like when you slide a bar magnet through a copper coil) induces an electric current. At planetary scale, Earth’s magnetic field induces ...

This magnetic field is very similar to the field that is produced by a common bar magnet. It is called a dipole because it has two poles at either end of the magnet. These endpoints are where the ...

In order to track the Earth's magnetic field, scientists treat it as if it were produced by a bar magnet, and then compare ...

In order to track the Earth's magnetic field, scientists treat it as if it were produced by a bar magnet, and then compare those results to the actual observed magnetic field. However, it's harder ...

Peer-Reviewed Publication University of Birmingham A new route to materials with complex ‘disordered’ magnetic properties at the quantum level has been produced by scientists for the first time.

In fact, China debuted a hybrid resistive/superconducting magnet in 2022 that achieved a 45.22 tesla field. On the other side of the world, the US National Lab's mini superconducting prototype ...

Once the WHAM team chilled the magnets down to operating temperature and applied a strong electrical current, the high-temperature superconductors produced a 17 tesla magnetic field.

The magnetic field around a circular loop of wire is similar to that of a bar magnet. When an electric current flows through the loop, it generates a magnetic field.

If you’ve ever found yourself wondering how those tool magnetizer/demagnetizer gadgets worked, [Electromagnetic Videos] has produced a pretty succinct and informative video on the subject. Wh… ...
