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

New research published in Physical Review Letters suggests that superconducting magnets used in dark matter detection ...

GCSE; CCEA Double Award; Magnetic fields - CCEA Magnetic field of a bar magnet. Magnetism and electromagnetism occur because of the magnetic fields around magnets and around electric currents.

Imagine a world where the weather forecast isn’t just a guess, but a button you can press. Picture farmers summoning rain for ...

The video explains the concepts of magnetic, electric, and gravitational fields using simple demonstrations. It shows how iron filings reveal the magnetic field around a magnet, how charged ...

Two German physicists have unveiled a compact magnet layout that outperforms the famed Halbach array, delivering stronger, ...

Physicists develop efficient alternatives to the classic Halbach design – with potential for a wide range of applications ...

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.

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 ...

Cutting a bar magnet in half won't get rid of its poles. It'll just produce two magnets, each with a north pole that will be attracted to the other magnet's south pole, and vice versa. It's this ...

Illustration of the global coronal magnetic field as the sun rotates. The background is the solar corona observed in extreme-ultraviolet waveband, with global coronal magnetic field maps measured ...
