6 The Discovery of the Electromagnetic Laws Always Keep an Open Mind

The relationship between electricity and magnetism was first observed in 1820 by Oersted in a public lecture at which he was demonstrating the "well known fact" that electricity and magnetism were completely independent phenomena. This time the experiment failed! - an electric current produced a magnetic effect. Oersted was observant enough to notice this effect, honest enough to admit it, and diligent enough to follow up and publish. Maxwell used these experiments to extend Newton's methods of modeling and mathematical analysis in the mechanical and visible world to the invisible world of electricity and magnetism and derived Maxwell's Laws which opened the doors to our modern age of electricity and electronics.
