Uniform and non-uniform gravitational fields

Physics Education, 2018
Abstract According to Newtonian mechanics, the gravitational fields created by bodies with spherical symmetry (such as planets) are non-uniform. This may create the impression to undergraduate physics students that uniform gravitational fields are just an approximation.

Electroemulsification in a Uniform Electric Field

Langmuir, 2015
Emulsification using electric fields is an easy alternative to flow-induced drop breakup, and the former is reported to be more effective and economical than the latter, especially when the medium phase is poorly conducting and highly viscous. The emulsification of a coarse water-in-oil emulsion in a uniform electric field is studied.

Electron diffusion in a non-uniform electric field and a uniform magnetic field

Acta Physica Sinica (Overseas Edition), 1996
A Monte Carlo simulation technique has been used to model the electron transport behavior, especially the electron diffusion motion, in the cathode fall region of a glow discharge under the influence of a non-uniform electric field and a transverse magnetic field perpendicular to the cathode sheath electric field.

Uniform Field Breakdown in Air

Nature, 1955
RECENT work by Llewellyn Jones and Parker1 on the steady-state current flow in a uniform field gap in air subjected to a steady d.c. potential has been interpreted in terms of the Townsend theory of breakdown involving a secondary or γ-process. Oscillographic observation, however, shows that, as the breakdown voltage is approached, relatively high ...

Modeling molecular response in uniform and non-uniform electric fields

The Journal of Chemical Physics, 2013
The response of a molecule to an electric field E, often a model of environment, can be expressed in terms of a sum of power series expansions. We investigate the accuracy and limits of applicability of this expression using one-, two-, and three-dimensional models of the hydrogen-bonded complex, ClH:NH3.

Ponderomotive ratchet in a uniform magnetic field

Physical Review E, 2005
We show how a ratchet effect, generally used in systems with periodic potentials, can also be practiced on charged particles by an ac field alone, in a background magnetic field near the cyclotron resonance. The effect relies entirely on the spatial inhomogeneity of the high-frequency drive, which produces a deterministic asymmetric ponderomotive ...

Line Sink in Uniform Magnetic Field

The Physics of Fluids, 1971
The motion of an inviscid, incompressible, and conducting fluid due to a line sink in a uniform strong magnetic field is considered. The solutions show that motion is confined in a narrow region parallel to the magnetic field. Such a motion for a point sink has erroneously been named as a wake or backward jet flow.
