Magnetic dipole model in the near-field
2015 IEEE International Conference on Information and Automation, 2015Magnetic dipole model is significant to calculate the magnetic strength of the magnet source. However, a restriction is that the distance from the testing position to the magnet's position must be much farther than the size of the magnet. The magnetic dipole model is not suitable for the near-filed around the magnet.

Magnetic field contribution to the Lorentz model
Journal of the Optical Society of America A, 2006The classical Lorentz model of dielectric dispersion is based on the microscopic Lorentz force relation and Newton's second law of motion for an ensemble of harmonically bound electrons. The magnetic field contribution in the Lorentz force relation is neglected because it is typically small in comparison with the electric field contribution.

AIP Conference Proceedings, 2007
This course is aimed at showing how to understand and solve problems of melt flow under magnetic fields during crystal growth from the melt. The course involves the following points. The first part of the course focuses on an analytical approach for determining the effects of external forces based on gravitational acceleration and of rotations of a ...

Electromagnet Model Through Magnetic Field Analysis
International Journal of Modelling and Simulation, 1987In this paper, parallel processing computer system models are considered, in which, each CPU service time of programs subdivides into independent parts (tasks) that can be processed in parallel.Dif...

Modeling magnetic catheters in external fields
The 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005We develop a mechanical model for catheters and other interventional devices which are steered by externally applied magnetic fields. Each device contains a permanent magnet near its distal tip. The external magnetostatic field, whose direction and magnitude can be selectively varied, is applied to the vicinity of the tissue where the medical procedure

A model of a magnetic field in the geomagnetosphere
Planetary and Space Science, 1972Abstract A new magnetospheric field model is proposed. The magnetospheric surface is considered to be a tangential discontinuity and is approximated by a paraboloid of revolution. The magnetic field within the magnetosphere has been obtained as a solution of the magnetostatics problem.

Magnetic fields with photon beams: Monte Carlo calculations for a model magnetic field
Medical Physics, 2000Strong transverse magnetic fields can produce very large dose enhancements and reductions in localized regions of a patient under irradiation by a photon beam. We have suggested a model magnetic field which can be expected to produce such large dose enhancements and reductions, and we have carried out EGS4 Monte Carlo calculations to examine this ...

A Model Of Magnetic Field On Supergranules
1996The magnetic fields in supergranules and in the chromospheric network have been studied by Kopp & Kuperus (1968), Gabriel (1976), Delache (1976), Simon, Weiss & Nye (1983) and Anzer & Galloway (1983).

Reviews of Geophysics, 1975
A review of the development of coronal magnetic field models is presented. Each model's assumptions are discussed with reference to their validity within the solar corona. It is pointed out how remarkable it is that electrodynamics is applicable on a large scale as well as on the small scale from which it originated.

Ising Model in a Magnetic Field
1997The calculation of the spin-spin correlation function G(x) = of the two-dimensional Ising Model in a magnetic field has been a long-standing problem of statistical mechanics. Solution of this problem has been recently obtained by using a quantum field theory approach based on the spectral representation method for correlation functions [1]. The aim of
