磁场环路定理中H的物理含义

On the Physical Meaning of H in Magnetic Circuits Theorem

几乎所有的大学物理教材都把磁场环路定理中的H仅理解为总磁场强度,即H是空间所有传导电流的贡献,其实这不是绝对的,它还可以理解为包围在闭合路径之内的传导电流在闭合路径上产生的磁场强度。

In almost all college physics textbooks, the H in Magnetic Circuits has been commonly understood as the total magnetic field intensity, which means the contribution of all the conduction current in a space. However, it can also be understood as the conduction current that is generated in a closed path and surrounded by the closed path.
