Scientists measured a chorus wave emerging from an unexpected place, and confirmed a key piece of a theory about how these ...

A magnetic field is the effect we can see from the movement of charges or the spin of electrons. The fields themselves can be static or changing. A field diagram can be used to show the interactions ...

Abstract: Theoretical values of the magnetic ... the length of the magnet. This theoretical formula is modified to fit experimental results at shorter distances as well so that it can serve as a ...

The reversal could actually have a beneficial effect on Earth. The sun is on the verge of a significant event: a magnetic field reversal. The sun undergoes such a reversal every 11 years ...

It was originally developed for CERN scientists. Rolex Magnetic fields are one of the most common factors negatively affecting the accuracy of a mechanical watch. Internal watch parts made of metal ...

The findings have significant implications for studying space weather and the relationship between the Sun and the Earth's ...

Abstract: This paper presents experimental and theoretical results on focusing a long electron beam with a permanent magnet structure which produces a periodic magnetic field along the axis of the ...

Swarm is a constellation of three satellites that study Earth's geomagnetic field. This magnetic field that extends ... by the sun's less active period around 2017. "These are among the smallest ...

Unlike the geographic North Pole, which marks a fixed location, the magnetic north pole’s position is determined by Earth’s magnetic field ... longitude that curve around Earth from top ...

Under the action of an external magnetic field, the spin polarization vector of the atom will do Larmor precession around the magnetic field ... placed tiny magnetic objects in the human body and ...

Charged particles will only experience a force in a magnetic field if they are moving. The direction of the force is both perpendicular to the direction of the magnetic field and the direction of the ...
