Magnetic Field of a Long Straight Wire

The magnetic field of a wire was first discovered during an experiment by Hans Christian Oersted (1777-1851) of Denmark in 1820. This experiment consisted of running a current through a wire and placing a compass underneath it to see if there was any effect. I am very interested in clean energy storage and production, which typically
