SelfInduction(自感应)(P645-647 The process that an induced emf appear in any coil in which the current is changing is called self-induction(由于自己线路中的电流的变化而在自 己的线路中产生感应电流的现象一一自感现象) If we establish a current l in the coil, the magnetic flux linkage Na is proportional to 1, ∝ Define proportionality constant is L, y=LIChapter 28 Inductance and Electromagnetic Oscillations 28-2. Self-Induction The process that an induced emf appear in any coil in which the current is changing is called self-induction (由于自己线路中的电流的变化而在自 己的线路中产生感应电流的现象－－自感现象). 1. Self-Induction (自感应)(P645-647): If we establish a current I in the coil, the magnetic flux linkage N is proportional to I,   I Define proportionality constant is L,  = LI
