工程电磁场计算中磁力线绘制问题的研究

Study on Magnetic Flux Plot in the Calculation of Engineering Electromagnetic Field

研究了工程电磁场计算中磁力线绘制的问题．通过严格的理论推导，首次给出了使磁场中磁力线的疏密程度能正确反映磁感应强度大小的条件，并给出了轴对称场和二维场中条件的具体形式，从理论和实际中，解决了使磁力线图准确反映磁感应强度的问题．最后结合具体实例，证明了本文所给条件的正确性与有效性．

This paper studies how to plot the magnetic flux distribution. The general conditions that make the line of magnetic force reflecting the intensity of magnetic field have been derived.The particular forms of the conditionS for axis symmetrical fields and 2 -D plane field have been given.The examPle given in this paper shows the correctness and the validity of the conditionS presented by this paper.
