If the continuity equation implies Maxwell’s equations, then charge conservation should be considered as the fundamental axiom underlying these equations. In this paper we show how Maxwell’s equations can be obtained from the continuity equa ...

... In this problem, the electric field from a distribution of charge in 3, 2, and 1 dimension has been found using Gauss's law. The most noteworthy feature of the three solutions is that in each case, there is a different relation of the field strength to the distance from the source of charge. In each ...

How Can Electricity Cause Magnetism?
... through wires, a magnetic field is formed. The strength of the magnetic field is amplified by wrapping the wire around an iron nail. The more turns of wire, the greater the magnetic effect. The magnetism only lasts while electrons are flowing through the wire. This helpful interaction is what allows ...

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.
