The structure and dynamics of the solar corona is dominated by the magnetic field. In most areas in the corona magnetic forces are so dominant that all non-magnetic forces like plasma pressure gradient and gravity can be neglected in the lowest order. This model assumption is called the force...
Using the small (co)reps and MEBRs, we construct a complete position-space theory of mean-field band topology in the 1,651 single (spinless) and double (spinful) SSGs – Magnetic Topological Quantum Chemistry (MTQC) – that subsumes the earlier theory of TQC5,6 [see Fig. 2]. The ...
Thus a different kind of magnetic field class should exist and be able to explain such anti-phase correlation. Indeed we can find the solution in the magnetic elements of Component III which are measured to be in anti-phase with the solar cycle and distributed all over the solar disk1,2....

Fig. 12.9.Flux density (B) versus magnetizing field (H) for the important classes of permanent magnets [43]. 7.2DC motors The two types are (i) brushed and (ii) brushless. The major features of brushed DC motors are shown inFig. 12.10. The coils are wound on a slotted iron rotor wi...
We have seen that the formula for toroidal field, given by (20), is able to account for some of the observed longitudinal drifts. Meanwhile, the poloidal component, [Math Processing Error] and [Math Processing Error], possibly acts as a restoring force. To quantify this, we measure the ...
The [FeIIICl4]- anion occupies sites between the [FeII(TCNE•-)(NCMe)2]+ layers. [Fe(TCNE)(NCMe)2][FeCl4] has a coercive field of 1730 Oe and a remnant magnetization of 7500 emuK/mol at 50 K. 展开 DOI: 10.1021/ja066744f 年份: 2006 ...
Self-adjoint extensions of the Dirac Hamiltonian in the magnetic-solenoid field and related exact solutions We study solutions of Dirac equation in the field of Aharonov-Bohm solenoid and a collinear uniform magnetic field. On this base we construct self-adjoint ... SP Gavrilov,DM Gitman,AA Smir...
Using the PIC method of microscopic particle simulation, the plasma magnetic nozzle effect and performance of the MPDT under different magnetic-field conditions were studied. The integrated experiment used demonstrated that, in conjunction with the superconducting coil, greater homogeneity and a stronger ...
Most students have learned in electromagnetics that larger \(N\) leads to more B field. This is true, all else equal. In design, however, the target inductance is usually fixed and larger \(N\) is necessarily accompanied by larger reluctance \(\mathcal{R}\). Because gap length must sca...
