abhenry, aH (s) (noun), abhenries (pl)
Abhenry is a medical term referring to the centimeter-gram-second electromagnetic unit of inductance, equal to 10-9 or one billionth of a henry (a standard unit of inductance in the meter-kilogram-second system), equivalent to that of an induced 1 volt in the presence of a current that is changing at a rate of 1 ampere per second: "When the scientists met, they exchanged notes about their theories of abhenry applications."

"The term, abhenry, was named for Joseph Henry (1797-1878), a U.S. scientist who discovered the electromagnetic phenomenon of self-inductance, and who also discovered mutual inductance, independently of Michael Faraday. His work on the electromagnetic relay was the basis of the electrical telegraph."

"Michael Faraday (1791-1867) was an English experimental scientist who was especially noted for his discoveries in electricity, including electromagnetic induction, the battery, the electric arc, and the dynamo."

"Faraday's work on induction formed the basis of modern electromagnetic technology, and his work on electrochemistry laid the basis for this other important modern industry."

"Faraday's law is a law of electromagnetic induction stating that the electromotive force induced in a circuit is proportional to the time rate of magnetic flux change linked with the circuit."
