The calculating method of space magnetic induction of circular permanent magnet in the field of magnetic biologY efiect． / 中国医学物理学杂志

ABSTRACT

Formulas, which are applied to the space magnetic induction of circular permanent magnet, are deduced from BiotSavart-Laplaces 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.
