An electromagnet is generated by a current flowing through a wire loop at the centre of the field.(more) Magnetic fields may be represented by continuous lines of force or magnetic flux that emerge from north-seeking magnetic poles and enter south-seeking magnetic poles. The density of the ...
1. A synchronous switching controlgear (20) for circuit breaker (3) which performs synchronous switching control for circuit breaker (3) connected to an electric power system circuit, along with a stationary induction electrical apparatus, comprising: residual magnetic flux calculation means (17);a ...
Since L is not tangent to the field line at P, this flux is of order \(\epsilon\), i. e. of the same order as the variation of L. Therefore, the action S is not stationary along any curve that does not coincide with a magnetic field line. As a result of these discussions, ...
Magnetic fields may be represented mathematically by quantities called vectors that have direction as well as magnitude. Two different vectors are in use to represent a magnetic field: one calledmagnetic flux density, or magneticinduction, is symbolized byB; the other, called themagnetic field streng...
flux tubesEvershed effectBased on the almost fibril state of magnetic flux in astrophysical bodies we present a study of the stability of magnetic flux tubes which are described by the thin flux tube approximation. A stationary flow is allowed in the tube which in equilibrium lies in a ...
Solar flares are the best examples of astrophysical magnetic reconnection in which the reconnection structure can be studied in detail. The structure is ma
determining a magnetic flux profile of the electromagnetic field; sensing a magnetic flux leakage past the susceptor within the chamber; generating a control field from a secondary compensation coil coupled to the chamber, wherein the control field controls the magnetic flux experienced by the cast ...
Stationary siphon flows in arched magnetic flux tubes are studied. A pressure difference between the two footpoints of the tubes, which are anchored below the solar surface, drives the flow along the tubes. The radiative heat exchange between the tube and its surroundings is taken into account....
Soft electromagnetic devices have great potential in soft robotics and biomedical applications. However, existing soft-magneto-electrical devices would have limited hybrid functions and suffer from damaging stress concentrations, delamination or material
were observed, with the measured length limited only by the magnetic local time coverage of the cusp traversal. The term “primary” is used here to indicate a long, quasi-stable X-line as opposed to a transient X-line or lines that might be produced in a Flux Transfer Event (FTE) (...
