wrote: Gauss' Law is for static electric charges and fields. It is usually used for problems in electrostatics, but it is not confined to such problems. The differential form of it is just one of the Maxwell equations: div E(x,t) = 4\pi\rho(x,t) Integrate it over a fixed surface and you get the integral form, which is Gauss's law. It is valid with time-dependent charge densities and time-dependent electric fields. --John |

I provided the actual quotes. If you wish, you can consult the same reference we BOTH used: "The Feynman Lectures on Physics," or I can rummage up that material again. 73's Richard Clark, KB7QHC |

Art Art, All I can say is that Dr. Davis is a lot smarter than the rest of us. He quickly recognized pure BS and bailed out from this discussion in a hurry. 73, Gene W4SZ |

Gauss's law with respect to statics is quite specific and easy to understand. What is so wrong in mathematical terms by adding the metric of time to the law so that curl can be accomodated? i.e. change from a conservative field where all vectors have zero length, to a electro magnetic equation by adding the words " the addition of time" which by providing a three dimensional field has the true inclusion of curl i.e. all vectors have value in length and direction. America denies the feasability of such an addition to an existing law which in essence is regarded as a new law without basis on this side of the pond.Are all countries of this mentallity? Art Because a static field does not produce an EM field(curl) only if that static charge is in motion. Motion would even include taking a charged body, say a pith ball and waving it back and forth. Electrons have a static charge but when they are in motion in a conductor they produce fields(curl). Electrons moving about an atom also produces fields but the net result of all the aoms moving about is zero. PLEASE REFERENCE THE GUASSIAN LAW ON STATICS. I still think you are confusing static with statistics. But Jimmie my friend, now you have an understanding of Gaussian law what is preventing you adding the metric of time or a length of time to the statics law? What is it that frightens you and other Americans about that little step? Start off my looking at it in pure mathematical terms and determine if the intent of the law is still not violated. Don't go beyond that at this time just consider the mathematics and get comfortable with it Art Because it is meaningless |
