Magnetic fields in the disk and halo of M 51
We propose and discuss a method to analyze the structures of regular magnetic fields in external spiral galaxies with allowance for a multi-layer distribution of magnetic field and thermal electron density in the source of polarized radio emission. Our method allows for both horizontal and vertical components of the regular magnetic field. This approach we applied to the analysis of polarizatio...
متن کاملThe effect of magnetic field on the magnetic property of Agar/Fe3O4 nanocomposite
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...
متن کاملThe Study of Improvement of Dispersive Soil Using Magnetic Field
In this study, the feasibility of using magnetic technology to reduce the dispersion of soil has been investigated. The reference treatment was potable water and 3 magnetic water devices (with different magnetic intensities) were used for magnetizing the potable water. The results showed that the magnetic field has a significant effect in order of 5 percent on increasing of magnesium concentrat...
متن کاملNew clues to the magnetic field structure of M 31
We observed 21 polarized background radio sources in the field of M31 at 1.365 GHz and 1.652 GHz, and determined their rotation measures (RMs). The RM data show that the regular magnetic field of the disk probably extends from about 5 kpc to 25 kpc from the center with similar structure. The RMs obtained from the polarized emission from M31 at λ6 cm and λ11 cm indicate that M31 might have a wea...
متن کاملEffect of static magnetic field on the hemodynamic properties of blood flow containing magnetic substances
The use of magnetic fields in targeted drug delivery, especially for treatment of cancers and tumoral regions, is one of the significant techniques in the field of modern methods of treatment. Considering that many vital biological tissues have been located deep in the body, then for targeted drug delivery and effective treatment in these tissues, it is required to bring therapeutic agent to th...
