I think Hans Christian Oersted discovered that electricity and magnetism are related.
Michael Farady is best known for his work in the field of electricity and magnetism. He discovered the effect of magnetism on light, discovered and named Diamagnetism, the behavior of substances in magnetic fields and he was the first to produce an electric current from

Magnesia
It was discovered in the stone age. Magnetic stones 'Lodestones' were used for navigation for years.
A notable series of investigations of the relationship between electricity and magnetism was conducted almost in parallel in England by Michael Faraday and in America by Joseph Henry. Both Faraday and Henry discovered the principle of the dynamo in 1830-31, for example. Although they independently discovered many of the same connections and devices, Faraday's work was to have the greater theoretical impact while Henry's had more immediate practical application.
