The Emergence of Magnetic Flux

Solar Physics, 1985
This paper first summarizes the morphology and dynamics of emerging flux regions and arch filament systems and then discusses detailed observations of a particular active region with emerging magnetic flux.

Magnetic flux compression Generators

Proceedings of the IEEE, 2004
Magnetic flux compression generators offer the largest pulsed power output per unit size or weight when compared with other more conventional systems. They have found widespread use as pulsed power sources for hydrodynamics programs and high magnetic field research at national laboratories or in commercial applications, including exploration for oil ...

Squeezing of magnetic flux in nanorings

Journal of Physics: Condensed Matter, 2012
We study superconducting and non-superconducting nanorings and look for non-classical features of magnetic flux passing through nanorings. We show that the magnetic flux can exhibit purely quantum properties in some peculiar states with quadrature squeezing.

Magnetic Flux Transport on the Sun

Science, 1989
Although most of the magnetic flux observed on the sun originates in the low-latitude sunspot belts, this flux is gradually dispersed over a much wider range of latitudes by supergranular convective motions and meridional circulation. Numerical simulations show how these transport processes interact over the 11-year sunspot cycle to produce a strong ...

Easy calculation of magnetic flux

European Journal of Physics, 1998
Summary: In this paper, we give a very simple geometrical method to facilitate the calculation of the magnetic flux in some common cases where the magnetic flux density \(B\) produced by an infinitely long, straight wire carrying a steady current \( I_0\) is considered. The method is also valid for vector fields with the same symmetry.

Does Magnetic Flux Submerge at Flux Cancelation Sites?

Solar Physics, 1999
Simultaneous measurements of the magnetic fields in the photosphere and chromosphere were used to investigate if magnetic flux is submerging at sites between adjacent opposite polarity magnetic network elements in which the flux is observed to decrease or ‘cancel’.

Crystals of magnetic flux

Reports on Progress in Physics, 1979
The magnetic field in certain strongly magnetic materials, i.e. type-II superconductors and highly anisotropic ferromagnetics, can acquire a modulation which is periodic in two dimensions. The material can be thought of as being filled with a two-dimensional crystal of magnetic flux.

A new magnetic flux meter

Electrical Engineering, 1937
THE MEASUREMENT of magnetic fields in air gaps by the existing methods, is almost as cumbersome as light measurements were before the introduction of the photronic cell or photoelectric tube into that field. This paper describes a meter for the measurement of magnetic flux which seems to parallel the advance made in the lighting field.

Magnetic Flux Distribution in Transformers

Transactions of the American Institute of Electrical Engineers, 1922
It is customary when discussing magnetic leakage in the transformer to consider the primary and secondary windings as having a counter e. m. f. induced by a flux surrounding the coil and having the core for a part of its path. This leakage flux is frequently represented by closed lines.
