从电磁感应的基本定律出发,探讨了感生电场对磁介质原子中轨道电子的作用,对于抗磁质的抗磁性给出了明晰的解释;根据所得公式,以常见的抗磁质铜为例,估算出了磁化率.这一定量计算结果,在数量级上与一般物理学文献中所公认的数值吻合得很好.
- Abstract:
-
Starting from the basic law of electromagnetic induction, the effect of induced electric field on orbital electrons in magnetic medium atoms is discussed, and a clear explanation is given for the antimagnetic diamagnetism. According to the obtained formula, the magnetic susceptibility is estimated by taking the common antimagnetic copper as an example. This quantitative calculation results are in good agreement with the accepted values in the general physics literature in terms of orders of magnitude.
