Inductance

Definition

The inductance is the physical measure, which defines the characteristic of a dipole that can store energy via a magnetic field; it is the physical size equal to the ratio of the flow coupled with the contour to the current that passes this contour.

1 henry is the inductance, which at a current of 1 ampere hooks up a magnetic flux of 1 weber.

1 henry is the inductance of a closed circuit in which an electromotive force of 1 volt is produced when the electric current in the circuit varies uniformly at the rate of 1 ampere per second.
