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 ...

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

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 ...

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 ...

Physicists Prof. Dr. Ingo Rehberg from the University of Bayreuth and Dr. Peter Blümler from Johannes Gutenberg University ...

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 ...

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 ...
