摘要
介绍沿轴向充磁的圆环形永磁片产生的磁场的解析计算方法,得出与圆环形永磁片同轴的圆所包围的磁通量和场内各点磁感应强度的计算公式,并与现有公式做了比较。这些公式为通过测量圆环形永磁片产生的磁场来检查它磁化强弱的工作提供了理论依据。
The method to analytically calculate the magnetic field generated by annular permanent magnetic sheet magnetized along its axis of symmetry is described. The computing formulae for the magnetic flux surrounded by the circum coaxial with annular permanent magnetic sheet and for the magnetizing induction intensity are shown and compared with the available formulae. These formulas offer the theoretical basis for the magnetization level detection of the annular permanent magnetic sheet through measuring the magnetic field generated by it.
