what is self induction?

self induction

Self induction is such a thing that when a current changes in a coil, an emf is also produced in the conductor, that is when the flux is produced when the conductor is given a curtain, and if the curtain is modified then fared According to the law of the flux, the emf induces when this phenomenon is called a self-induction or induced emf. The emf coming in is always opposite direction, in this way emf produced by the opposition is called a counter emf or a self-induction.
