3 Electric Currents from Magnetism
... the current is zero. At 270°, the loop is parallel to the magnetic field. The current is at its maximum. However, because the sides of the loop are in opposite locations, the current in the loop is in the opposite direction. As the loop continues to rotate, the current continues to change direction. ...

History of electromagnetic theory
For a chronological guide to this subject, see Timeline of electromagnetic theory.The history of electromagnetic theory begins with ancient measures to deal with atmospheric electricity, in particular lightning. People then had little understanding of electricity, and were unable to scientifically explain the phenomena. In the 19th century there was a unification of the history of electric theory with the history of magnetic theory. It became clear that electricity should be treated jointly with magnetism, because wherever electricity is in motion, magnetism is also present. Magnetism was not fully explained until the idea of magnetic induction was developed. Electricity was not fully explained until the idea of electric charge was developed.
