【摘要】 提出一种求解各向异性磁介质中电流磁场的新方法,通过求解各向异性磁介质中圆电流环的磁矢势A分布,求出其磁感应强度B分布.结果表明,各向同性磁介质中圆电流环在远场点的磁矢势公式,与已知的结果一致;磁矩m在各向同性介质中的P点产生的磁感应强度,其结果也是预料之中.更多还原

【Abstract】 In this paper,a new method to solve the magnetic field produced by current in anisotropic magnetic medium is presented.The magnetic induction intensity distribution B is obtained by solving its magnetic vector potential A distribution of current-carrying circular circuit in anisotropic medium.Results indicated that the magnetic vector formulation of current-carrying circular circuit in anisotropic medium at distant field is consistent with the known result.The result of magnetic induction intensity generated by the magnetism moment m at P in anisotropic medium is also anticipated.更多还原
