CHAPTER 3 QUIZ – ELECTROMAGNETISM
... An ELECTROMAGNET is a solenoid with iron in the middle of it. An instrument used to detect small currents is called a GALVANOMETER. OERSTED found that an electric current created a magnetic field. A long coil of wire with many loops is called a SOLENOID. ELECTROMAGNETISM is the relationship between ...

... What is an Electromagnet? When an electric current is passed through a coil of wire wrapped around a metal core, a very strong magnetic field is produced. This is called an electromagnet. The more coils wrapped around the core, the stronger the magnetic field that is produced. This stronger mag ...

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.
