Chapter 3 GAUSS` LAW
... Gauss’ Law actually is one of Maxwell’s four laws of electromagnetism. Gauss’ Law is completely equivalent to Coulomb’s law for electrostatics or for slowly moving charges. However, Gauss’ law is more general and applies to electric fields arising from rapidly moving and accelerating charges. Really ...

Physics on the Guitar - Xraise Cornell
... At the core of magnetic pickups are magnets. Each magnet is oriented so that an imaginary line through the north and south poles will intersect with the string above it. A thin copper wire coiled around the magnet so that the axis of the coil aligns with the N-S axis of the magnet. The basic physics ...

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.
