inductance (symbol H) Property of an electric circuit or component that produces an electromotive force (emf) after a change in the current. The SI unit is the henry (symbol H). Self-inductance (symbol L) occurs when the current flows through the circuit or component, and mutual inductance (symbol M) when current flows through two circuits or components that are linked magnetically. See also electromagnetic induction

in·duc·tance / inˈdəktəns/ • n. Physics the property of an electric conductor or circuit that causes an electromotive force to be generated by a change in the current flowing: the inductance of the winding | an inductance of 40 mH. ∎  a component with this property.
