Question

Consider $I_{1}$ and $I_{2}$ are the currents flowing simultaneously in two nearby coils 1 and 2 , respectively. If $L_{1}=$ self inductance of coil $1, M_{12}=$ mutual inductance of coil 1 with respect to coil 2 , then the value of induced emf in coil 1 will be\

Professor PC Thomas Classes · Answer

(b) : Induce emf in coil 1 , will be due to the current flowing in itself (self induction) and due to the current flowing in the second coil due to $I_{2}$ (mutual induction) Induced emf due to $I_{1}$ on coil 1:
