The numerical simulation of the development a streamer discharge in gap with an external longitudinal magnetic field was used to demonstrate self-focusing such discharges. Self-focusing is caused by sharp deceleration radial ionization wave due change electron energy distribution function, decrease average energy, rate gas ionization, and mobility crossed electric fields as compared case withou...

<sec>Electric phenomena and magnetic are inseparable. The field affects the ionization balance spatial distribution of plasma. A new type plasma discharges has been found in nitrogen gas under sub atmospheric pressure condition without external field. Because its regular helical propagation pattern, it is called (HP) plume. Although a great deal research carried out on key characteristics...

The magnetic field, applied to a size-quantized system produces equilibrium persistent current non-uniformly distributed across the system. The distributions of dia-and para-magnetic currents and magnetic field in a quantum well is found. We discuss the possibility of observation of field distribution by means of NMR. Traditionally, the magnetic field, penetrating into the system with spatial q...
