The meaning of FIELD CURRENT is the current supplied to the field windings of a generator or motor to establish the magnetic field for its operation.
Simplex Wave WindingCentral SlotWidest Magnetic Peak AreaInduction Coil SensorThe DC generator is widely used in the fields of industry motor control and energy transfer, and the simplex wave winding (SWW) is the main winding pattern of the DC generator. In this paper, a brief introduction to ...
The electron plasma density and the Faraday rotation angle in plasma were calculated from images of the three-channel polarimeter. The magnetic field was reconstructed with Abel transform, and the current was estimated using a simple model. Several shots with wire-array Z pinches at 0.5–1.5 MA ...
One single-layer and two four-layer example winding structures are used to illustrate the impact of excitation frequency on the magnetic field intensity and current density distributions in transformer windings. By plotting the distributions as phasors in three-dimensional isometric plots, greater insight...
A problem of the irreversible entry of the Abrikosov vortex ring, induced by the self-field of a transport current, into a long type-II superconductor cylinder of arbitrary radius R is solved exactly in the London approximation. The magnetic field and current distribution for the toroidal vortex...
Further, the effect of shaping the magnetic field from an expanding one to a mirror shaped field by means of the downstream coil has been investigated. The downstream density and the plasma potential increase significantly when all the magnetic field lines in the source are passing also through ...
Definition of magnetic field and relaxation time The magnetic field \(\mathbf {H}\) relates to the energy density \(\varepsilon\) as \(\mathbf {H}=-\partial \varepsilon /\partial (M \mathbf {m})\), and therefore, is obtained from Eq. (1) as $$\begin{aligned} \mathbf {H}=\...
for helping to procure this special coated conductor from early production. This work was performed at the National High Magnetic Field Laboratory, which is supported by National Science Foundation Cooperative Agreement DMR-1644779 and the State of Florida. A part of S.H.’s analysis work was ...
Current induced by external magnetic field, "Indeed, current density functional theory has been used to study the formation of an electron crystal (Wigner crystal) at very high magnetic field [18]"[4] External(applied) current External current vs. SOT vs. Chirality ...
The microstructures of Nb-Ti-Zr sheets were investigated to make clear the relation between the microstructures and the applied magnetic field vs critical current density characteristics. The results are summarized as follows: (1) The ratio of Jc(\varparallel)Jc(⊥) are in proportion as the rati...
