Magnetoconvection simulations on mesogranule and granule scales near the solar surface are used to study the effect of convective motions on magnetic fields: the sweeping of magnetic flux into downflow lanes, the twisting of magnetic field lines, and the emergence and disappearance of magnetic flux tubes. Fromweak seed fields, convective motions produce highly intermittent magnetic fields in th...

In this article, the second quantization method has been used to investigate some thermodynamic properties of spin-polarized metallic nanowire in the presence of magnetic field at zero temperature. We have been observed that in different magnetic field, the equilibrium energy of system increases as the density increases. The spin-polarization parameter corresponding to the equilibrium state of ...

following a magnetic survey in saghande yazd region, the existance of a relatively important dike shape anomaly was detected. in the present study, this anomaly has been interpreted by the werner deconvolution method and parker standard curves. the location and depth of the uper surface of magnetic dike has been calculated by the werner method using a series of profiles perpendicular to the str...

[1] The Equatorial Electrojet (EEJ) produces a strong magnetic signal in measurements of the low-orbiting CHAMP satellite. Six years of data with more than 30,000 dayside equator crossings provide a unique data basis to study this current system. In addition to scalar measurements used in previous studies, we have also inverted vector magnetic field measurements to gain accurate meridional prof...

The Trans Bay Cable (TBC) is a ±200-kilovolt (kV), 400 MW 85-km long High Voltage Direct Current (DC) buried transmission line linking Pittsburg, CA with San Francisco, CA (SF) beneath the San Francisco Estuary. The TBC runs parallel to the migratory route of various marine species, including green sturgeon, Chinook salmon, and steelhead trout. In July and August 2014, an extensive series of ma...

Ordinary differential equations describing the self-similar collapse of a rotating, magnetized, selfgravitating and isothermal filament are derived. Explicit homologous solutions are studied with special emphasis on the bifurcation that occurs at the magnetosonic critical point. It is shown that there is a critical value for the toroidal magnetic field slope at the origin above which no bifurca...

A high-precision spectral motional Stark effect (MSE) diagnostic provides internal magnetic field measurements for Madison Symmetric Torus (MST) plasmas. Currently, MST uses two spatial views--on the magnetic axis and on the midminor (off-axis) radius, the latter added recently. A new analysis scheme has been developed to infer both the pitch angle and the magnitude of the magnetic field from M...
