It is established that a particle bearing an oscillating electric charge can exhibit transverse drift in a homogeneous magnetic field. This drift has a resonance character and cannot be eliminated even at small amplitudes of charge oscillations....
Magnetic force can cause a charged particle to move in a circular or spiral path. Cosmic rays are energetic charged particles in outer space, some of which approach the Earth. They can be forced into spiral paths by the Earth’s magnetic field. Protons in giant acce...
A general study has been made of the bound states of a charged particle in a static field which behaves as the dipole form asymptotically. When the field i... O,H,Crawford - 《Proceedings of the Physical Society》 被引量: 79发表: 2002年 Electric field of a pointlike charge in a stron...

1. If a charged particle moves in a straight line through some region of space, can you say that the magnetic field in that region is necessarily zero?Problems & Exercises 1. What is the direction of the magnetic force on a positive charge that moves as shown in each ...
The interaction between a strong plasma wave and a multicomponent stream of charged particles in the presence of a magnetic field is investigated numerically. It is shown that, under certain conditions, the plasma wave may accelerate the more rarefied component to ultrarelativistic energies. It is ...
