磁生物效应研究中圆片永磁磁源空间磁感强度的计算方法

The calculating method of space magnetic induction of circular permanent magnet in the field of magnetic biology effect．

本文根据电磁学中的比奥－－沙伐－－拉普拉斯定律，推倒出了圆片永磁磁源空间磁感强度的计算公式；并使用数值积分和计算机程序，建立了该公式的计算方法；最后通过实例计算，得出了圆片永磁磁源空间磁感强度的量值分布。为磁生物效应研究中磁源的使用提供了理论依据。

Formulas which are applied to the space magnetic induction of circular permanent magnet are deduced from Biot－Savart－Laplace＇s law in electromagnetics． The calculating methods of the formulas are set up with numerical integral and computer program． The space quantity distribution of magnetic induction of a circular permanent magnet is obtained through an objective example． These provide theory basis for the magnet application in the field of magnetic biology effect．
