Note-A-Rific: Induction So far we know that electricity and magnetism are related in at least two ways: 1. An electric current produces a magnetic field. 2. A magnetic field exerts a force on moving electric charges. Both of these facts were discovered between 1820-1821. Because of this, scientists began to wonder if a magnetic field could be used in some way to produce an electric current. By 1831 the American Joseph Henry and the Englishman Michael Faraday independently showed it could happen. o Henry discovered it first, but Faraday published his results first. o One of the “rules” in science is that it doesn’t matter who actually discovered something first, it matters who got published in a scientific journal first. o It sort of counts as being “registered” as the creator of that idea. o You’ve probably never seen one of these scientific journals, since they are read mostly by people like university professors. The design Faraday came up with was like this…
