Henry ¹ Scientific  

1. American physicist who studied electromagnetic phenomena. He discovered electrical induction independently of Michael Faraday, and constructed a small electromagnetic motor in 1829. He also developed a system of weather forecasting based on meteorological observations. The henry unit of inductance is named for him.

henry ² Scientific  

/ hĕn′rē /

1. A SI derived unit of electrical inductance, especially of transformers and inductance coils. A current changing at the rate of one ampere per second in a circuit with an inductance of one henry induces an electromotive force of one volt.
