37.3 Generators and Alternating Current 37 Electromagnetic Induction
... 37.1 Electromagnetic Induction The amount of voltage induced depends on how quickly the magnetic field lines are traversed by the wire. • Very slow motion produces hardly any voltage at all. • Quick motion induces a greater voltage. Increasing the number of loops of wire that move in a magnetic fiel ...

... The magnitude F of the force that each of two point charges q1 and q2 a distance r apart exerts on the other is directly proportional to the product of the charges (q1 q2 ) and inversely proportional to the square of the distance between them (r2 ). The relationship is expressed symbolically as F =k ...

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.
