... Gauss’ Law for velocity If we integrate over a complete closed surface, then we have dV/dt (created or destroyed) = v dA . However, we know mass (and water) can’t be created or destroyed, so v dA = 0. Electric field is a vector just like velocity is a vector. The sources of electric field are c ...

Representing Vector Fields Using Field Line Diagrams
... An array of field lines is called a field line diagram, and it is a way of representing both the direction and the strength of a vector field. The direction is found by focusing on an individual field line, as above. The strength is found by looking at the density of field lines. For example, the fi ...

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.
