We describe the characteristics and evolution of the magnetic field and chromospheric emission in an active region core observed by the Solar Optical Telescope (SOT) on Hinode. Consistent with previous studies, we find that the moss is unipolar, the spatial distribution of magnetic flux evolves slowly, and that the magnetic field is only moderately inclined. We also show that the field line inc...

Low-intensity magnetic separators are widely used in the research works and the industry. Advancement in the magnetic separation techniques has led to an expansion in the application of this method in different fields such as enrichment of magnetic mineral, wastewater treatment, and medicine transfer in the human body. In the mineral processing industry, the main application of wet magnetic sep...

virial theorem is important for understanding stellar structures. it produces an interesting connection between magnetic and gravitational energies. using the general form of the virial theorem including the magnetic field (toroidal magnetic field), we may explain the solar dynamo model in relation to variations of the magnetic and gravitational energies. we emphasize the role of the gravitatio...

Magnetic field  improved germination parameters. The germination of Catharanthus roseus seeds is lost under salinity conditions. The effect of different strengths of magnetic field and exposure durations on the germination of C. roseus seeds under salinity conditions (19 mS cm-1) were investigated. The experiment was conducted  with factorial arrangement based on a completely randomized design ...

A large fraction of major flares occur in active regions that exhibit a configuration. The formation and disintegration of configurations is very important in understanding the evolution of photospheric magnetic fields. In this paper we study the relationship between the change in spot structures and associated major flares. We present a new observational result that part of penumbral segments ...

Agar/Fe3O4 nanocomposites were synthesized in the presence of an external magnetic field (~ 0.4 Tesla) and their characteristics were compared with the samples synthesized without considering the external magnetic field. In this study we used Fe2+ and Fe3+ for synthesizing Fe3O4 magnetic nanoparticles in the presence of agar as polymeric additive, by co-precipitation technique. Vibrating sample...

Abstract We investigate the orientation of photospheric magnetic fields in solar polar region using observations from Helioseismic and Magnetic Imager (HMI). Inside small patches significant polarization, inferred field vectors at 1″ scale appear to systematically deviate radial direction. Most tilt toward pole; all are more inclined plane sky compared vector. These results, however, depend on ...

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 ...
