Magnetic fluxAstrophysicsAn investigation is made of the relationship between photospheric 'filigree' light points, line-center brightness, and magnetic field, as inferred from sets of individual images and films showing a distinct difference between two classes of magnetic regions. While in the first ...
Where q is the charge of the particle, v is its velocity and B is the magnetic flux vector. The relation between magnetic field and magnetic flux is given by the following equation B = u X H = uH Where B is the magnetic flux, H is the density of magnetic field and u is the perm...
In free space the relation between magnetic field and magnetic flux density is simple and magnetic flux density is proportional to magnetic field strength, (1)B→=μ0H→, where μ0 is the permeability of free space and has value μ0 = 4π × 10−7 H/m. On the other hand, for dif...
Magnetic field line lengths inside interplanetary magnetic flux ropesdoi:10.1002/2015JA021133CMEsICMEsGrad‐ShafranovfluxropeWindWe report on the detailed and systematic study of field line twist and length distributions within magnetic flux ropes embedded in interplanetary coronal mass ejections (ICMEs)....
The analysis is performed both for the cases of natural convection alone taken into account and of combination with Marangoni convection. As a result, it is shown that, assuming steady state, the surface flow velocity at the point of interest varies with the applied magnetic field intensity ...
Magnetic reconnection can occur when two plasmas, having anti-parallel components of the magnetic field, encounter each other. In the reconnection plane, the anti-parallel component of the field is annihilated and its energy released in the plasma. Here, we investigate through laboratory experiments ...
Coronal holes are solar regions with low soft X-ray or low extreme ultraviolet intensities. The magnetic fields from coronal holes extend far away from the Sun, and thus they are identified as regions with open magnetic field lines. Coronal holes are con
We saw in Section III.D that the vortices in a Type II superconductor are about two penetration depths apart when the applied magnetic field Bapp reaches a value ≈1.8Bc1. For Bapp>2Bc1, there is a strong overlap of the magnetic fields from neighboring vortices, and the internal field Bin...
are classified as active regions (Component-I). Small bulks with weak magnetic fields in quiet regions are classified as small-scall elements. These small-scale elements further form four groups according to their flux and relation with the solar cycle. Pixels with heliocentric angles larger than ...
The relationship between the X-ray flux and the radio flux from cosmic objects is investigated. We consider the emission from energetic electrons on the condition in which a plasma and a magnetic field exist. As energetic electrons under the circumstances emit both X-rays by the bremsstrahlung ...
