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 ...

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 ...

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.

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

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

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 ...

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 ...

Earth’s magnetic field is a dipole field with two poles, like a bar magnet. When the poles flip, it could cause chaos for future humans.

The maximum field tolerance of these MRAM devices is between a few tens of milliTesla, mT, to 100mT, depending upon the MRAM target application. 10mT in SI units is 100G in CGS units of magnetic ...
