Hans Oersted was preparing his class of physics in the University of Copenhaguen, one evening of April, 1820, when, on having moved a compass next to a cable that was leading electrical current, it noticed that the needle was moving up to staying in a position perpendicular to the direction of the cable. Later, a big quantity of times repeated the experiment, confirming the phenomenon. For the first time a connection had been between the electricity and the magnetism, in an accident that can be considered to be the birth of the electromagnetism.
THE CURRENT THAT CIRCULATES ALONG A DRIVER IS CAPABLE OF CREATING A MAGNETIC FIELD AROUND HIM.
