Magnetic and electric fields of rotating charge distributions

American Journal of Physics, 1982
A charge distribution with axial symmetry is allowed to rotate with constant angular velocity around the axis of symmetry. The magnetic field of the resultant current density is calculated in terms of the electrostatic field of the charge distribution.

Electrical field distribution in transformer oil

IEEE Transactions on Electrical Insulation, 1992
Developments in Kerr electro-optic measurement technology at the laboratory have made possible high resolution electric field measurements in nonpolar liquids. The electric field distribution in transformer oil has been studied at service stress levels in both the transient and steady state.

Electric field distribution on knife-edge field emitters

Applied Physics Letters, 2007
Conformal mapping is used to calculate the electric field on a knife-edge cathode, modeled as a rectangular ridge on a flat surface. It is found that the field enhancement factor scales approximately as the square root of the height-to-width ratio of the knife edge.

Electric field distribution in aluminum in strong magnetic fields

Soviet Journal of Low Temperature Physics, 1978
An anomalous electric field distribution was found in high purity aluminum under strong magnetic fields, produced by transverse displacement of current lines due to longitudinal inhomogeneity in H. The admissable inhomogeneity with use of the four-electrode method is determined by the effective magnetic field, with increase in which the requirement for

Electric field distributions in neuronal membranes

Mathematical Biosciences, 1975
Abstract The “instantaneous” current-voltage relationship of a neuronal membrane is examined in the light of the Planckian and Goldmanian limits of the membrane's electric field distribution and a detailed model of facilitated ionic transport through the membrane.

Field ionization distribution curves and the local electric field

Journal of Physics: Condensed Matter, 1992
Ionization probabilities of imaging gas molecules under field ion microscope conditions are calculated and compared with previous calculated and experimental results. It is shown that it is necessary to include the possibility of ionization before reaching the region close to the sample in the calculation of the curves rather than just considering the ...

Electric Field Distribution in a Dense Plasma

The Physics of Fluids, 1960
A calculation is presented of the probability distribution function of the electric field at the center of an ion or atom in a plasma in the high ion density limit. In this limit, it is possible to take into account rigorously the effect of the Coulomb interactions on the distribution function.

Spatial distribution of the electric field for field emission microtriodes

Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures Processing, Measurement, and Phenomena, 1996
The spatial distribution of the electric field on the emitter is studied for field emission microtriodes (FEMTs). An analytical three-dimensional FEMT model is used to show that the electric field on the emitter as a function of the angular position E(φ) can be written as a sum of an anode field term Ea(φ) and a gate field term Eg(φ).
