摘要
三维静电场、静磁场的数值计算不是一个新问题,已有大量论文或专著发表,但在有源场中存在多个孤立悬浮电位或磁位的导电体或导磁体的情况下,三维静电场或静磁场的计算迄今尚无一个较好的算法可资应用。 业已发展的计算三维静电磁场的方法,有些要对整个场域进行计算。
We present here the calculation of 3D static fields with the existance of isolated arbitrary shape condutors and magnets by the surface charge density method. As an example, the magnetic field distribution in the reaction chamber of MRIE equipment is calculated. Numerical results are in good agreement with the experimental values.
