【摘要】 对于均匀磁化的磁介质内的球形空腔问题.通常认为腔外仍为均匀磁场 H₀,腔内磁场强度为 H=（（μx+2） /3） H₀. 本文指出上述结果的错误,并通过求解满足一定边值关系的Laplace方程获得问题的正确结果.更多还原

【Abstract】 As for the problem of the spherical hole inside the evenly magnetized magnetic medium,people usually think that the outside of the hole still remains to be an evenly mag netic field H₀,and the magnetic field strength inside the hole is H₀=（μ_r+2） /（3） H₀. This article points out the error of the above conclusion and at the same time,reaches the correct solution of this problem by finding the solution of the Laplece equation with a certain boundary condition.更多还原
