Article #1: How Does An Electrical Generator Work?
... An electrical generator is a simple device that moves a huge magnet near a wire to create a steady flow of electrons, known as an electric current. In large power generators, the coils remain stationary, and the magnetic field rotates. This produces the same effect. The magnet rotates with the turbi ...

... Static Electricity occurs when there is a change of matter in an object. Almost all the time matter is electrically neutral. That means that it has the same amount of positive charges and negative charges. When these electrical charges builds up on an object the results are static electricity. ...

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.
