Static Electricity: Electric Charge & Electric Field
... So E = kQ/r2 , this is the amount of the electric field around a charge Q at a distance r away from Q. This is the electric field from a point source (as opposed to an electric field between 2 parallel plates which we'll talk about soon). ...

... In 1831 Michael Faraday in England and, independently, Joseph Henry in the United States demonstrated they could create a current in wires without batteries as long as the wires were in the vicinity of a changing magnetic field. In particular, if a wire loop is placed in a magnetic field and the str ...

Faraday paradox
This article describes the Faraday paradox in electromagnetism. There are many Faraday paradoxs in electrochemistry: see Faraday paradox (electrochemistry).The Faraday paradox (or Faraday's paradox) is any experiment in which Michael Faraday's law of electromagnetic induction appears to predict an incorrect result. The paradoxes fall into two classes:1. Faraday's law predicts that there will be zero EMF but there is a non-zero EMF.2. Faraday's law predicts that there will be a non-zero EMF but there is a zero EMF.Faraday deduced this law in 1831, after inventing the first electromagnetic generator or dynamo, but was never satisfied with his own explanation of the paradox.
