... Electromagnets can be very powerful. Since they are formed using an electric current, they can also be turned on and off. An electromagnet can be created by winding a wire around a metal rod and running electric current through the wire. Conductors are made out of metals, although electricity can tr ...

... Passing a current through a piece of wire causes a magnetic field to form around a wire (electromagnetism). The strength of the magnetic field could be greater if you put a piece of copper inside the wire. This is called an electromagnet. ...

Faraday discovered that, whenever the magnetic field about an electromagnet was made to grow and collapse by closing and opening the electric circuit of which it was a part, an electric current could be detected in a separate conductor nearby. Moving a permanent magnet into and out of a coil of wire ...

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.
