The 3D calculation of the magnetic fi eld around a model current carrying conductor and ferromagnetic plate has been performed by means integral equations in quasistatic case. There is good agreement between calculated measured results. equation approach very effective space which distant from source there are not many different types materials. conductivity permeability materials assumed to be...

We investigate the strongly magnetized strange baryonic matter in a relativistic mean-…eld theory. We …rst take into account the hidden strange mesons and the …eld-dependent meson-baryon coupling constants. In low-density region the strongly magnetized neutron star (NS) matter is nearly iso-symmetric. The equation of state (EOS) therefore becomes softer than that of the normal NS matter. Becaus...

The nonlinear evolution of magnetized Keplerian shear ows is simulated in a local, three-dimensional model, including the eeects of compressibility and stratiication. Supersonic ows are initially generated by the Balbus-Hawley magnetic shear instability. The resulting ows regenerate a turbulent magnetic eld which, in turn, reinforces the turbulence. Thus, the system acts like a dynamo that gene...

The method of positron lifetime measurement was used to analyse the in uence of a magnetic eld on the kinetics of corrosion defect formation in near-surface layers of iron, titanium as well as S20 and S0H18N9 steel grades. The listed metals, which belong to ferroand paramagnetic materials, have di erent sensitivity to corrosion. It was found that not only the presence of a magnetic eld, but als...

Data on the relation of past climate variations and changes in the geomagnetic +eld can contribute to the research on a cosmic ray–climate link. This paper presents a synthesis of geological and astrophysical results about the link of magnetic +eld variations and Earth’s climate and external forcing. On millennial timescales, geomagnetic intensity lows are apparently in phase with times of low ...

We present 1420 MHz polarization images of a 2.5 × 2.5 region around the planetary nebula (PN) Sh 2-216. The images are taken from the Canadian Galactic Plane Survey (CGPS). An arc of low polarized intensity (size 0.2×0.7) appears prominently in the north-east portion of the visible disk of Sh 2-216, coincident with the optically identified interaction region between the PN and the interstellar...

By means of He's homotopy perturbation method (HPM) an approximate solution of velocity eld is derived for the ow in straight pipes of non-Newtonian uid obeying the Sisko model. The nonlinear equations governing the ow in pipe are for- mulated and analyzed, using homotopy perturbation method due to He. Furthermore, the obtained solutions for velocity eld is graphically sketched...

We study theoretically the lattice instability in the spin gap systems under magnetic eld. With the magnetic eld larger than a critical value h c1 , the spin gap is collapsed and the magnetization arises. We found that the lattice distortion occurs in the spin-ladder at an incommensurate wavevector corresponding to the magnetization, while it does not occur in the Haldane system. At low tempera...
