You all time about Maxwell's hypothesis. But Maxwell wrote: "The general type of a stress is not suitable as a representation of a magnetic force, because a line of magnetic force has direction and intensity, but has no third qufility indicating any difference between the sides of the line, which would be analogous to that observed in the case of polarized light[2]." From: http://en.wikisource.org/wiki/On_Phy...Lines_of_Force To explain the light polarization Maxwell assumed that the current in the wire create the magnetic whirl around the wire (The same for displacement current in the space). Maxwell's waves are polarized. Now you know that the dipoles are "polarized" (not waves). S* |

From: http://en.wikisource.org/wiki/On_Phy...Lines_of_Force Yeah, and Maxwell was talking about magnetic fields, not electromagnetic fields, in that sentence. To explain the light polarization Maxwell assumed that the current in the wire create the magnetic whirl around the wire (The same for displacement current in the space). Gibberish. Maxwell's waves are polarized. Now you know that the dipoles are "polarized" (not waves). S* More gibberish. -- Jim Pennino Remove .spam.sux to reply. |

S*- Hide quoted text - - Show quoted text - of course dipoles are polarized, dipoles = two poles, if you have two poles you have to have at least 2 points, and 2 points define a line and that line defines the polarization. qed. |
