Lesson 20: Faraday's Law of Induction Between 1820-1821 scientists discovered most of what we have been looking at in recent lessons. Because it was obvious that moving charges and magnetic fields were able to interact with each other, scientists began to wonder if a magnetic field could be used to produce an electric current. By 1831 the American Joseph Henry and the Englishman Michael Faraday had each showed it could happen. Henry discovered it first, but Faraday published his results first, so who gets the credit? 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. It sort of counts as being “registered” as the creator of that idea. So, Faraday gets the official credit and we call this effect Faraday's Law of Induction . The experimental design that Faraday and Henry used was basically the same. .. If the switch on the left side is closed, current will flow through the loops on that side.
