This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to audio speakers. Oh, and without it we’d live in eternal darkness.
Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it encompasses both the intrinsic spin of particles and their orbital motion ...

The universe's first magnetic fields were 'comparable' to the human brain — and still linger within the 'cosmic web'
Such magnetic fields are "comparable to magnetism generated by [the electrical ... of the cosmic web with the James Webb Space Telescope (JWST) could allow them to create more powerful simulations to ...
Basically, every square inch of Earth emits a magnetic field -- and this field is then modulated by man-made concrete and steel structures. If you have a map of these magnetic fields, and a ...
The oldest firm age yet for Earth's magnetic field suggests that it developed before a solid planetary core, 3.7 billion years ago. When you purchase through links on our site, we may earn an ...
Primordial magnetic fields, billions of times weaker than a fridge magnet, may have left lasting imprints on the Universe.
