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

But axions were pushed aside as the WIMPs hypothesis gained more steam. Back-of-the-envelope calculations showed that the ...

Cosmic rays hit Earth’s atmosphere all the time, but most are too weak to detect. A few, however, carry extreme energy: more than a million times what particle accelerators on Earth can produce. A new ...

Worked Example A proton enters a magnetic field (B = 4 × 10 − 3 T) at the speed of 2.5 × 10 6 m / s. Determine the magnitude and direction of the force on the proton as it enters the field. To work ...

Calculating the effect of a moving particle through a magnetic field After a particle has been accelerated through a potential difference, particle accelerators use a series of magnets to change the ...

This article investigates the binary collision between an ion and a charged dust particle in the plasma in the presence of a uniform magnetic field. The trajectories of ions are calculated using the ...

South Atlantic Anomaly and Earth's magnetic field The SAA was first discovered back in 1958 and to this day is still watched closely by experts at NASA. In recent years, NASA has revealed it can ...

NASA’s recent mission has unveiled Earth’s ambipolar electric field, crucial for understanding atmospheric dynamics and exploring other habitable worlds. A rocket team reports the first successful ...

The most recent period of weak magnetic field – including a temporary switch in north and south poles – began 42,000 years ago and lasted about 1,000 years.

A quiver consists of directed arrows and nodes. The arrows represent the quantum fields (matter fields), while the nodes represent the interactions – e.g., strong, weak, or electromagnetic – between ...
