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

Did you know Earth's magnetic field is on the move? Recent studies reveal it's shifting at an astonishing rate—10 times ...

Scientists at TU Delft have unlocked a key quantum effect in graphene without using any magnetic fields, paving the way for ...

The research team has identified atacamite as a material with magnetocaloric properties. Natural crystals have long ...

There's a magnet in a secure room in central Tokyo. It's an electromagnet, the kind that generates a magnetic field when electrical current flows through it. The last time the scientists who operate ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth.

The acceptable zeros of the potential of the electrical fields produced by certain dipole distributions in homogeneous volume conductors is discussed. A bridge circuit is described by which a solution ...

And that’s exactly what happened, at least some of the time. When the young sharks were exposed to the magnetic field of the place they were caught, off Florida’s Gulf Coast, they swam in ...

A method is presented for controlling the field-directed self-assembly of colloidal magnetic core–shell nanoparticles into three-dimensional (3D) crystalline superstructures with nanoscale feature ...

Surprising discovery shows a strong link between Earth's magnetic field and atmospheric oxygen levels by Sanjukta Mondal, Phys.org edited by Sadie Harley, reviewed by Robert Egan Editors' notes ...

New compact semianalytical expressions of the scalar potential and magnetic fields produced by a radially polarized permanent magnet are described in this paper by using Coulombian approach. It uses ...

In 2010 its rare earths and magnet supplies were cut-off by China for two months over a territorial dispute. It’s why rare earths have been on the critical minerals lists of North America, Europe and ...
