Abstract
A theoretical method for studying the behavior of magnetic field intensity inside a rectangular plate with orthotropic anisotropic conductivity was presented. Firstly, based on Maxwell’s equations, the mathematical model for the magnetic field in the plate was established. Then, the governing equation for determining the magnetic field intensity was solved by double Fourier sinusoidal transformation. Furthermore, taking graphite rectangular plate as an example, the magnetic field intensity inside the plate was simulated and the behavior of the magnetic field was introduced in detail. Lastly, the effects of the plate’s size, the external excitation frequency and the conductivity of graphite on the internal magnetic field intensity were analyzed.
Highlights
At present, the study of magnetic field in material is mostly based on the fact that the distribution of material’s conductivity is isotropic, that is, the conductivity is constant
One was the study of thin-layer material such as thin film with anisotropic conductivity,3,4 semiconductor monolayer heterostructure5 and two-dimensional atomic crystal material;6,7 two, the research in medical fields such as biomedical imaging and brain tissue;8–10 and another was to explore the significance of electromagnetic exploration by studying the anisotropic crustal medium
We investigated the behavior of the magnetic field intensity inside a rectangular plate with orthotropic conductivity aiming at preparing for the study on the material’s eddy current
Summary
The study of magnetic field in material is mostly based on the fact that the distribution of material’s conductivity is isotropic, that is, the conductivity is constant. The anisotropy of conductivity is objective, the conductivity of the earth medium is anisotropic and the conductivity of most organism tissues is anisotropic..
