| 摘 要： | 本文把一个抽象的电磁场定律具体化,阐述了安培环路定律在磁场屏蔽工程实践中的应用.通过在屏蔽体中引入与干扰电流大小相等、方向相反的返回电流,使合成磁场相互抵消,达到了磁屏蔽的目的.通过这种方法能够加深学生对安培环路定律的理解,掌握该定律的具体应用.同时也可激发学生对工程电磁场学科的兴趣,提高学生理论联系实际的能力.

| Abstract: | This paper concretizes the abstract electromagnetic field theorem and expounds the application of ampere circuit theorem in magnetic field shielding.By means of introducing the same size and opposite direction of return current in shield compared with interference current,it can counter-balance mutually of resultant magnetic field and achieve the purpose of magnetic shielding.Applying this method into teaching,it will enhance the understanding of Ampere circuit theorem and make the undergraduates master the... |
