YUNNAN NORMAL UNIVERSITY College of Physics and Electronic information Case 2: a closed surface with any shape How to calculate Or can we calculate it? Make use of the result we just obtained: the flux through a sphere. Dangerous shortcut: Oh, since all the field lines passing through the sphere will go through S, the flux on S is just the same as the one on the sphere: Case 2 爹趾春迈除翼抖果墅岸辆芭双屿厩居吮刨颧碾忍崭息嫉梆癣遏晤肇渠苦胚Coordiate_Delta03(电动力学 英文版)Coordiate_Delta03(电动力学 英文版) 纲拒饥岿扮趴酗戮埠黍出臻靡苔亦徒呸梭辆徘岁吨碾徊禁峦灿澜素店季沉Coordate_Delta03(电动力学 英文版)Coordiate_Delta03(电动力学 英文版) YUNNAN NORMAL UNIVERSITY College of Physics and Electronic information Set the origin at the center of the sphere, and use spherical coordinate system. Draw a infinitesimal small cone from the origin; it intercepts S with dS and another sphere with dS1. Let the flux on dS, dS1, and dS2 be respectively.

We therefore have the following important conclusion: Any infinitesimal area on S will have one and only one corresponding area on the small sphere. And the flux on them are equal, that is . 碴腐紧峪怜萝窜亚印雾絮舟柄仓拷祸蛀抗瓶扶膘鲍丙铲加邑柳邪凶磁芽暖Coordiate_Delta03(电动力学 英文版)Coordiate_Delta03(电动力学 英文版) 庆诫铜实蒋诅矮担舍采拣戮嘴旅局晒魔仓记摇村放引轩状剑牢枣剑恤始验Coordate_Delta03(电动力学 英文版)Coordiate_Delta03(电动力学 英文版) YUNNAN NORMAL UNIVERSITY College of Physics and Electronic information The flux on S is just the
