Current profile control by alternating current magnetic helicity injection
Current profile control by ac magnetic helicity injection is computationally investigated in a reversed field pinch ~RFP!. Three-dimensional resistive magnetohydrodynamics ~MHD! computation is employed to study the nonlinear MHD. During ac helicity injection, when toroidal and poloidal surface voltages are oscillated out of phase, the parallel electric field is maintained positive over a majori...
متن کاملAlternating current magnetic susceptibility of a ferronematic
We report on experimental studies focusing on the dynamic ac magnetic susceptibility of a ferronematic. It has been shown recently, that in the isotropic phase of a ferronematic, a weak dc bias magnetic field of a few oersteds increases the ac magnetic susceptibility. This increment vanishes irreversibly if the substance is cooled down to the nematic phase, but can be reinduced by applying the ...
متن کاملAlternating current driven instability in magnetic junctions.
An effect is considered of alternating (high-frequency) current on the spin-valve-type magnetic junction configuration. The stability with respect to small fluctuations is investigated in the macrospin approximation. When the current frequency is close to the eigenfrequency (precession frequency) of the free layer, parametric resonance occurs. Both collinear configurations, antiparallel and par...
متن کاملGlow discharge plasma switch controlled by a small magnetic field
A cold plasma switch scheme with opening and closing capabilities is reported. An externally applied magnetic field causes a low pressure hollow cathode discharge to transition from a low impedance mode sustained by oscillating beam electrons into a virtually collisionless high impedance mode. The impedance of a 10 A discharge was demonstrated to increase by 20 with the application of a field o...
متن کاملA review of the alternating current field measurement inspection technique
This paper describes the principles of the a.c. field measurement technique, a non-contacting electromagnetic method of crack detection and sizing in metals. The development of the technique is covered, followed by examples of some of the many different applications the technique has been used for, including multi-sensor arrays for rapid manual inspection or for deployment by robotic manipulato...
