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

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 ...

If true, that could explain oddities in Neptune and Uranus’ magnetic fields. ... and electrostatic repulsion, where charged atoms or groups within the molecule repel one another.

Because of the repulsion force, they aren’t hanging straight down. ... Wire 2 is in the presence of this magnetic field, so it experiences a force that pulls it toward wire 1.

With their innovative design, tokamak reactors are leading the charge in fusion research, aiming to unlock the potential of nuclear fusion for global energy needs.

Sometimes, the magnetic fields are relatively weak, like the ones that thread their way through the spiral arms of galaxies. Sometimes, they're medium-strength, like Earth's.

“We find that both exhibit strong linearly increasing trends, coupled with a large surge in magnitude between 330 and 220 ...

The earth’s magnetic field is about 0.05mT, or 0.5G. Magnetic measurements in household and work environments demonstrate measurements below 0.1mT, or 1G, at distances greater than 16cm, ...

The solar magnetic field is the primary driver of solar storms and flares. As society grows increasingly reliant on technology, this space weather poses threats to power grids, ...

According to the ESA, “Our magnetic field is largely generated by an ocean of superheated, swirling liquid iron that makes up the outer core around 1,864 miles beneath our feet.
