Quasi-dipole Magnetic Fields

The Quasi-Near Fields of Dipole Antennas

The electricand magnetic-field components produced by vertical and horizontal dipole antenuas (both electric and magnetic types) located over, on, or below the surface of a semi -Mte conducting medium are derived and presented for the quasi-near range. (The measurement distance is much greater than an earth skin depth, but much less than a free-space wavelength.) Previously derived results are ...

Torsional Oscillations of Relativistic Stars with Dipole Magnetic Fields

We present the formalism and numerical results for torsional oscillations of relativistic stars endowed with a strong dipole magnetic field, assumed to be confined to the crust. In our approach, we focus on axisymmetric modes and neglect higher-order couplings induced by the magnetic field. We do a systematic search of parameter space by computing torsional mode frequencies for various values o...

Quasi-two-dimensional excitons in finite magnetic fields

We present a theoretical and experimental investigation of the effects of a magnetic field on quasi-twodimensional excitons. We calculate the internal structures and dispersion relations of spatially direct and indirect excitons in single and coupled quantum wells in a magnetic field perpendicular to the well plane. We find a sharp transition from a hydrogenlike exciton to a magnetoexciton with...

Dipole - Dipole Interactions of Charged - Magnetic Grains

Numerical simulation of chainlike cluster movement of feeble magnetic particles by induced magnetic dipole moment under high magnetic fields.

In this paper, the motion of a chainlike cluster of feeble magnetic particles induced by high magnetic field is discussed on the basis of the results of numerical simulations. The simulations were performed on glass particles with a diameter of 0.8 mm; and the viscosity, applied magnetic field and magnetic properties of the surrounding medium were changed. In addition to the magnetic field and ...
