However, a most interesting effect appears when a charged particle in a field is followed where the lines of force converge toward one another. By applying first approximation, the direction from which slow charged particles should enter the atmosphere; converging rays, forming auroral coronas, ...
Believing, as we do, that electric currents are due to the motion of charged particles, we naturally enquire what magnetic field is produced by a single moving particle, and what forces it experiences when it moves in a magnetic field. To take the second question first, let us postulate a...

In the longitudinal direction, the particles may be trapped by strong field inhomogeneities 1 or simply by having the field lines closed within the gas volume.doi:10.1038/181331a0B. LEHNERTNature Publishing Group UKNatureLEHNERT, B. "Confinement of Charged Particles by a Magnetic Field". Na- ...

The Heliospheric Magnetic Field Probed with Fast Charged ParticlesThe Heliospheric Magnetic Field Probed with Fast Charged ParticlesWe discuss the physics of the transport of energetic charged particles in the heliosphere. We put this in the context of using fast charged particles as probes of the hel...
Anomalous diffusion of field lines and charged particles in Arnold-Beltrami-Childress force-free magnetic fields The cosmic magnetic fields in regions of low plasma pressure and large currents, such as in interstellar space and gaseous nebulae, are force-free in the s... AK Ram,B Dasgupta,V Kr...
Aurora is caused by Earth’s magnetic field. The aurora is a natural light display predominantly seen in high-latitude regions, caused by the interaction of the Earth's magnetic field with charged particles from the solar wind. These particles are guided by the Earth's magnetic field towards ...
A magnet produces a vector field, the magnetic field, at all points in the space around it. It can be defined by measuring the force the field exerts on a moving charged particle, such as an electron. The force (F) is equal to the charge (q) times the speed of the particle times ...
The motion of a charged particle in a nonuniform magnetic field is complex. If a magnetic field is strong at the ends and weak in the middle, the particles oscillate back and forth between the end points. Such a field can be produced by two current loops at the ends of the “bottle”...
