Definition of Mutual induction
Shared enlistment is the peculiarity when a curl prompts an EMF across it because of the pace of progress of current in a contiguous loop with the end goal that the ongoing stream in one loop is connected to the next curl.
Definition of Mutual Inductance
Mutual inductance is the ratio of the induced emf across one coil to the rate of change of current in another adjacent coil such that the flux linkage of the two coils is likely.
Mutual Induction:
Whenever there is a time-varying current in a coil, the time-varying flux self-couples with the coil and causes a self-induced emf across the coil. This emf is seen as the voltage drop across the coil or induct-or. But it is not practical to connect the coil only to its own changing flux. When a different current flows simultaneously in a second coil placed near the first coil, the flux generated by the second coil may also connect the first one. This different flux linkage to the second coil will also induce an emf on the first coil. This phenomenon is called mutual induction and the emf induced in one coil due to time variation in any other coil is called mutual induced emf. If the first coil is also connected to a time-varying source, the net emf of the first coil is the sum of the self-induced and mutually induced emf.
Coefficient of Mutual Induction or Mutual Inductance
Let us consider a coil of self-inductance L1 and another coil of self-inductance L2. Now we will also consider that there is a low reluctance magnetic core connecting these two coils in such a way that the entire flux generated by one coil will connect the other coil. This means that there will be no flux leakage in the system.
