... makes compasses work. If you were to put a compass close to a strong magnetic field (example: an electromagnet) the compass would be affected by that field more than the earth’s magnetic field. The next time you are wondering what pole of a magnetic you are looking at, you can use a compass to figur ...

... An electrical power business uses electric meters to quantify the number of electricity consumed by each. It bills the customer for the level of electricity and reads the meter occasionally. The most frequent kind is basically an electrical induction motor that drives a string of geared wheels linke ...

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.
