WebAboutTranscript. When changing current in one coil induces an EMF in the other, the phenomenon is called mutual induction. The strength of the EMF induced depends on the mutual inductance of the pair of coils. The S.I. unit of mutual inductance is Henry, the same as that of self-inductance. Created by Mahesh Shenoy. WebElectromagnetic induction is the process of inducing an electromotive force by moving a charge-carrying conductor (for example, metal wire) in a magnetic field. When an electrical conductor moves through a magnetic field, it crosses the magnetic field lines, causing the magnetic field to change.
