Maxwell`s Equations
... Note that Maxwell’s Equations predict a unique velocity for the electromagnetic waves, which is just c, the speed of light. Thus, for Maxwell’s equations to be correct in all reference frames we are led to Einstein’s theory of Special Relativity! The wavenumber k is actually a vector, as is the velo ...

Recitation #4 Solution
... Since there is +Q inside shell, there must be –Q at r = R1 to make the total charge inside for R1 < r < R2 equal to zero, i.e. –Q on the inside surface of the shell. Since there was initially no net charge on the conductor, there must be +Q amount of charge some place to cancel the –Q on the inside ...

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.
