Oersted’s experience was to demonstrate the connection between electrical and magnetic phenomena. Placing a conductor with a drain and a magnetic arrow next to it. The scientist passed a current through a conductor and observed the turn of a magnetic needle towards the conductor. With a reverse current, the arrow turned 180 degrees. Thus, proving the connection between a magnet and a conductor with current.
