标题[问题] 电磁学 AMPERE'S CIRCUITAL LAW
时间Tue May 17 00:06:49 2011
题目是:
Two infinite extent current sheets exist at z=-2m and at z=+2m. The top sheet
has a uniform current density K= 2ay A/m and the bottom one has K= -3ay A/m
Find H at (a) (0,0,4 m), (b)(0,0,0 m), (c)(0,0,-4 m)
例题都是一个 infinite, 课本後面较难的题目出现这题，顿时不知该怎麽解。
算式: H=1/2*K*aN 不知道是不是用这个，请问有人会可以大概解一下吗:)
谢谢大大
