... a volcano has produced many lava flows over a past period, scientists can analyze the magnetizations of the various flows and from them get an idea on how the direction of the local Earth's field varied in the past. Surprisingly, this procedure suggested that times existed when the magnetization had ...

An insulator is the substance that does not permit electric charges to move. e.g., glass, plastic, and rubber There are substances that fall in an intermediate position between conductors and insulators. These substances are called semiconductors such as silicon and germanium. With the properties of ...

Chapter 23: Electric Fields
... Chapter 23: Electric Fields Previously (Ch. 22) we have seen that two electric charges will either attract or repel each other. How is it that one electric charge even knows about the existence of the other charge?? Based on an idea of Michael Faraday’s we say that one of the charges sets up an elec ...

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.
