... Activities using magnets can feature at all levels. Students will have some knowledge of magnets, since they are common around homes, but students often expect magnets to attract any metal object rather than only iron and steel. Magnets have no effect on aluminium, brass, silver or copper. Students ...

Chapter 21 The Electric Field I: Discrete Charge Distributions
... A popular classroom demonstration consists of rubbing a plastic rod with fur to give the rod charge, and then placing the rod near an empty soda can that is on its side (Figure 21-36). Explain why the can will roll toward the rod. Determine the Concept Because the can is grounded, the presence of th ...

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.
