Why does the pyramidal shape resonate various energy fields?
The very shape of the pyramid is an amplified-receiver or resonator of various kinds of energy fields, i.e. electro-magnetic waves, cosmic rays, electrical discharges, gravitational waves, etc., surrounding our planet and which are in the air around and within the pyramid.
Inside the pyramid the received energies, interact with one another.
A pyramid also creates a spherical field like a 3D globe of harmonic vibrations – where the wave patterns are synchronous and rhythmic – around itself. Everything within that field will move towards the harmony. 
How does the pyramid create a spherical field of harmonic vibrations around itself?
In a magnetic field like the inside of a pyramid, the produced magnetism is in a direction opposite to that of iron where the field-direction is outward from the North Pole and inward to the South Pole of a magnet. In other words in a pyramid the direction of its magnetic field is outward from the South Pole of the pyramid and inwards to the North Pole.
The pyramid shape generates a spin field from its apex for electrons, meaning that they can move in an angular momentum, i.e. around their own axis. So, if moving or kinetic energy enters the pyramid at the top opening, this can be taken as the North Pole of its magnetic field and as the pyramid emits energy from its middle, this can then be taken as the South Pole of its magnetic field.
Once it entered into the pyramid, the energy bounces from the equal sides of its walls while the five angles of the pyramid project a beam of radiation towards the center where the energy is collected or pooled to form the “fire in the middle” (the word pyramid is translated as ‘fire in the middle’). These energies all combine in the center or King’s chamber area of, i.e. the Great Pyramid. The molecules or atoms in this area absorb these energies by resonance.
The corners are then, in effect, a type of nano-wave radiator. As the energy increases, the electron orbits start to expand; as more energy is absorbed, more expansion occurs and as the energy increases, there is an increase in circulation and finally we have a highly saturated energy atmosphere in the wave bands around 10 nm. These energies also radiate outwards from the corners of the pyramid. 
Pyramid energy is a life-giving force called bio-cosmic energy, which allows for the pyramid to become a kind of cosmic antenna that tunes into vast energy sources, receives the energy and changes itself into a magnetic field. While most of the positive energy is focused within and beneath the pyramid, some is also diffused from the five points or angles. Many people who have stood on top of the Great Pyramid have described sensing a high energy field or electrical charge.
How does this occur?
Depending on the material it is built with, i.e. some kind of crystal or stone such as granite or marble, a pyramid will create a spherical field of harmonic vibrations around itself. Rose granite, which was used in the construction of the King’s Chamber of the Great Pyramid, is one of the most paramagnetic substances that has the ability to alter the magnetic field in the area it occupies.
Limestone, which covered the Great Pyramid on the outside, is a diamagnetic substance in that it is repelled by both poles of a magnet – being repelled then, the energy moves right through its walls to the outside.Caeli Francisco - HumansAreFree
