energia9, have you built this or are you going to build it? The concept is very much like what I'm doing right now with growing plants in the dark.

energia9, I am thrilled to see others investing the time, energy and $$ to experiment. Cool. For those of you who are reading this and not contributing, I suggest you do the same and share. Its always fun to see other people's pyramids!    I will upload some pictures and videos of mine for you soon.

screaminvern, your compass experiment is similar to ones I have performed in the past with my steel frame pyramid. I noticed that sometimes those magnetic variations are due to improper connections at the vertices of the shape itself.  How have you attached the rising edges of the copper pipe to the four corners of the square base? Are the solenoids that are wound around all the edges CW or CCW, perhaps a mix of both? 

Just as an aside, the magnetic field of Earth may appear to be only be unidirectional (i.e. North/South) but you must also take into consideration the West wind.    Most people do not know this, but there is a rotational magnetic field always moving from West to East accross the surface of the Earth in the phi direction (spherical coordinates). So, if there is to be any variation at all, it should be on the western edge of the pyramid.

pyramidtime, the sloping tubes are just setting in the "cup like" fixtures I attached at each corner of the base, and the cups are ferrous. The solenoids are all wound CW.

screaminvern, if you are going to build a copper pyramid you have to use ONLY copper.    This forum thread is called Pyramid material right? You have presented a perfect opportunity to bring up some valuable information. Even though copper and steel are both conductors they have very different electromagnetic properties. For example, copper is diamagnetic, while steel is ferromagnetic. This can throw off the entire musical harmony of it all, the whole electromagnetic radiation pattern. 

Cool, so the solenoids are all wound CW. Now determine for each edge, each solenoid, what the directionality of the magnetic flux is flowing through it. You have to use the Right Hand Grip Rule (RHGR) to tell you where North is on each end of the solenoid. But you probably already know that!  You may have overlooked configuration of the solenoids.    Think of the square base as a separate circuit, you want the solenoids to point S-N, S-N, S-N, S-N all the way around the base in a CCW manner. This way the result is a dipole pointing skyward toward the pyramid peak via the RGHR again. 

As an aside, I promised a picture of my pyramid.  Here is one picture with two pyramids, one made of aluminum and the other copper. This was taken two years ago, when I was a young lad and experimenting with the Peter Grandics patent.  I have come a long way since then ...
