Magnetic Field Data Correction in Space for Modelling the Lithospheric Magnetic Field
Space Science Reviews, 2016The Earth’s magnetic field as it is measured by low-Earth orbit satellites such as Swarm and CHAMP results from the superposition of internal and external source fields overlapping in time and in space. The Earth’s lithospheric field is one of the weakest sources detectable from space and its accurate description requires treatments of rapidly-varying ...

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.

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.

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 ...

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

Fast Magnetic Field Modeling for Shielding Systems
IEEE Transactions on Magnetics, 2013In this paper, a new iterative algorithm for the analysis of properties of magnetic shielding systems is proposed. Since such shielding systems for low frequency applications are composed of thin-walled shells with magnetic materials of high permeability, the thin shell approximation is adopted and a numerical integral formulation of the ensuing ...

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.

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 hybrid magnetic field model for axisymmetric magnets
2013 IEEE/ASME International Conference on Advanced Intelligent Mechatronics, 2013A hybrid model, synergistically fusing the accuracy of artificial neutral networks (ANNs) and the efficiency of the single magnetic dipole (MD) model, is presented to characterize the magnetic field of axisymmetric cylindrical permanent magnets. While the MD model is widely used due to its simplicity, its efficacy reduces dramatically near the source ...
