MAXWELL that Einstein struggled for in vain. For those that feel that mechanical laws of Newton cannot be used with respech to electrical subjects( ala Roy) here is a chance for you to prove your point. Regards Art Unwin, *a limey no less I made an error int he above statement which I need to correct. The particles used in the transition from Gauss are STATIC particles of the inter galaxial kind which have the propensity to settle on diamagnetic materials without rejection This being the same material from which antennas are made of. When a majority of free electron are in a ELECTROSTATIC field created by a change in voltage levitation takes place on static particles. This is somewhat opposite to ELECTROMAGNETIC levitation altho there are also other differences which I need not to go into at this time. The circuit that providees such conditions is a tank circuit where the radiator must be a multiple of one wave length to ensure equilibrium is maintained within the Gaussian field Art Let me clear this up a bit further because of the related posts Articles that refer to frogs elc being levitated are refering to the magnetic field of 1 to 10 tesla where the leviatated material diamagnetic. Articles refering to the electron gun should realise that the electrons are not in the majority and in fact the electrons are part and parcel of the material being heated by being in orbit. It takes considerable power to remove the electron from orbit from its native material and like a tungsten lamp dissapates over time which when DC is used is called "notching" The same thing happens of course when heating is done by AC except we have two notches in different places instead of one which is why DC driven lamps only have a half life. So let me reiterate.In a electron gun the electron is torn away from its orbit which diminishes the mass of the parent material. With respect to a passive or static particle the particle is levitated from a diamagnetic surface beyond the arbitary Gaussian field where when the electrostatic field diminishes the surface is repopulated. That is if the operation is not in a vacuum! Ofcourse some particles are already in motion when the electrostatic field dissapates such that some particles have not had time to escape the arbitary field, so I suggest these return to the diamagnetic material where all the surface space has now been taken by replacement static particles thus leaving only the space below the surface for them to rest and decay. I hope that makes things clearer. Regards Art Unwin KB9MZ.....xg |

Hi Art, The week is up, and your research reveals you have gone off into the ditch. You have utterly failed to account for the necessity of the "work function" when it comes to separating an electron from any surface (your appeal to diamagnetics is specious). I could go deeper into your absurdity of mass reduction above by asking you how much mass would a filament be reduced by with a typical cathode current of 1 Ampere - but I will save the board the boredom of your string of non-answers when you are invited to specifically support your own specific statements. 73's Richard Clark, KB7QHC |

Discussed things in a civil manner where we were able to resolve the outstanding matters and close this thread. You need to go elseware to spew your comments and irritate people or start another thread, this subject has been resolved to my satisfaction Have a great new year incase I miss your missives Art |

"The week is up and your (Art`s) search reveals you have gone off into the ditch." Look for the answer to how electrons escape a material on page 172 of Terman`s 1955 opus. On page 173 Terman writes: "It can be considered as an evaporation of electrons in which the energy the electron must give up in escaping corresponds to the latent heat of vaporization of the liquid."

Best regards, Richard Harrison, KB5WZI And he then goes on to say, "The properties of matter are such that thermionic emission of electrons does not become appreciable until temperatures of the order of 1000 degrees K or higher are reached." The quotes are from the "Thermionic Emission of Electrons" section. Roy Lewallen, W7EL |
