What did Faraday and Henry discover?

Michael Faraday, A British physicist and chemist, best known for his discoveries of electromagnetic induction and of the laws of electrolysis. The research that established Faraday as the foremost experimental scientist of his day was, however, in the fields of electricity and magnetism. In 1821 he plotted the magnetic field around a conductor carrying an electric current. In 1831 Faraday followed this accomplishment with the discovery of electromagnetic induction and in the same year demonstrated the induction of one electric current by another.

Joseph Henry,an American scientist. He build electromagnets, Henry discovered the electromagnetic phenomenon of self- inductance . He also discovered mutual inductance independently of Micheal Faraday, though Faraday was the first to publish his results. Henry's work on the electromagnetic relay.
