context_page_description: The henry is the SI derived unit of electrical inductance. If a current of 1 ampere flowing through a coil produces flux linkage of 1 weber turn, that coil has a self inductance of 1 henry.‌ The unit is named after Joseph Henry, the American scientist who discovered electromagnetic induction independently of and at about the same time as Michael Faraday in England.
