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

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 ...

Spacecraft magnetic field modeling
IEEE Transactions on Magnetics, 1977Excellent results have recently been obtained using a new analysis technique developed by this author to model spacecraft magnetic fields. The technique described here is capable of producing accurate mathematical models of magnetic fields surrounding almost any magnetic object.

Magnetization of Ising Model in Nonzero Magnetic Field
Journal of Mathematical Physics, 1969Knowing only the zero-field magnetization (e.g., Yang's result) of the Ising model in any number of dimensions, one can construct a lower bound on m(h), the magnetization in finite field. Knowledge of u, the internal energy per bond, enables a more efficient lower bound to be constructed.

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.

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.
