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

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

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.

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 ...

That magnet is strong, representing roughly 75 percent of the intensity of Earth's magnetic field at the surface. Of course, a bar magnet is not a perfect representation — it's actually electric ...

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

Static magnetic field therapy: In this, you touch a magnet to your skin. You might wear a magnetic bracelet or other magnetized jewelry. It could be a bandage with a magnet in it, or you may wear ...

Earth's magnetic field can be visualized if you imagine a large bar magnet inside our planet, roughly aligned with Earth's axis. Each end of the magnet lies relatively close (about 10 degrees) to ...

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 ...

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 ...

As a result, ferromagnetic materials can be easily magnetized when exposed to a magnetic field. Materials like iron and magnetite, an oxide of iron (Fe 3 O 4), naturally have their magnetic fields ...
