ABSTRACT

Objective:

In Order to study on biological effects of rotary magnetic field (RMF) conveniently and precisely,a digital-controlled instrument for generating RMF,which is based on a single-chip microcomputer,is developed.

Methods:

The precise frequency of RMF is controlled by using microcomputer to drive step motor,and intensity of magnetic field is measured by using 10-bit Analog-to-Digital(A/D) Converter module which is integrated in microcomputer.According,the technique of LCD screen to display relative information,such as,frequency,intensity of magnetic field,time of timer,is applied.Additionally, touching buttons,which is simple and convenience to use,is selected.

Results:

This instrument works very well with high precise frequency,and its operation is simple.As a example for this instrument,that biological effect of RMF on the the prostate about SD rat is significantly is found.

Conclusion:

This instrument may be used to research and study on biological effects of RMF widely.
