... 70) When the magnet is falling through either pipe, the magnetic field is static and unchanging relative to what? a) The magnet itself b) The pipes c) Neither the magnet itself or the pipes 71) Now suppose we, in our minds, divide the either pipe into a series of horizontal sections. These sections ...

... Magnetic poles come in two types. Opposites attract, it operates through space, and it can do work. It is not surprising that the two are related. Moving charge creates a magnetic field. Since all magnetic fields have north and south poles, the magnetic field created by moving charge also has polari ...

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.
