What is Henry in physics?

In the field of physics, the Henry (often denoted by the symbol ‘H’) can be defined as the unit of electrical inductance. As per the International System of Units (often abbreviated to SI), one henry is equal to the self-inductance of a coil through which an electric current of magnitude one ampere is flowing and the resulting flux linkage created by it is equal to one weber. The SI unit of electrical inductance is named after the American scientist Joseph Henry (who is also credited with the discovery of electromagnetic induction since he discovered it independently and at approximately the same time as the English scientist Michael Faraday). Alternately, one Henry can be defined as the inductance of an electrical circuit which changes at the rate of one ampere per second and the resulting electromotive force (EMF) across the inductor has a magnitude of one volt.
