磁疗用方片磁源空间磁场定量分析

Quantification Analysis of Space Fields on Square Magnets Using for Magnetic Therapy

磁疗是利用磁场对人体患病部位或有关穴位进行作用,从而达到治病或保健目的的一种物理疗法。近年来随着非药物疗法的兴起,磁疗也越来越引起人们的关注。由于磁疗常用各种永磁磁源空间磁场分布比较复杂,因此磁场的作用剂量问题一直困扰着有关研究人员。本文采用有限元数值计算建立了方片磁源空间磁场的计算方法,得出方片磁源空间磁场的矢量磁位、磁感强度、磁场能量密度量值、磁感强度等值线和磁力线,为方片磁源的使用提供了多参数的量值依据,对磁疗的定量应用有重要的指导意义。

Magnetic therapy is a kind of physics curing method, which uses magnetic fields to effect tissues and acupoints of human body. People are attention to magnetic therapy more and more with development of non - drugs cure methods. Since various magnets have different space magnetic fields distribution, quantitative application is a trouble to researchers in magnetic therapy. In this article, we established space fields calculating method on square magnets with the finite element method, getting magnetic vector potential, magnetic induction, magnetic energy density, magnetic induction equivalence lines and magnetic force lines on square magnets. These provided quantitative values of different parameters on square magnets, being an important guidance for quantitative application of magnetic therapy.
