Elementary charge. Elementary charge as a unit[edit] In some natural unit systems, such as the system of atomic units, e functions as the unit of electric charge, that is e is equal to 1 e in those unit systems.

Elementary charge

The use of elementary charge as a unit was promoted by George Johnstone Stoney in 1874 for the first system of natural units, called Stoney units.[4] Later, he proposed the name electron for this unit. Conductors and Insulators. Charges and Fields 2.04. Electromagnetic induction. Electromagnetic induction is the production of a potential difference (voltage) across a conductor when it is exposed to a varying magnetic field.

Electromagnetic induction

It is described mathematically by Faraday's law of induction, named after Michael Faraday who is generally credited with the discovery of induction in 1831. History[edit] A diagram of Faraday's iron ring apparatus.
