The Plasma Reaction Rod "PPR" or "Rod" for short, is a length of cold pressed mild steal with a fuel specific Length, Diameter and Profile.
The "Rod" floats inside the Reactor Core / Fuel Pipe. Being held in place by a naturally occurring magnetic bearing.
When one has established the required conditions to induce a plasma reaction, the electrical and magnetic fields that "pick up" the rod also leave an imprint on it
What one then observes with a compass is called the Reversing Field effect.
The Reversing Field Effect.
A normal length of steel bar has a North end and a South end, this doesn't change no matter which way up you hold it.
When a rod from a GEET reactor is held vertically (TIP Down) & a compass is brought toward the Rod from the East or West:
The Back of the Rod reads NORTH The Tip end reads SOUTH.
When the Rod is inverted (Tip Up)
The Back of the Rod is SOUTH and the Tip NORTH.
The magnetic polarity of the Rod's ends appears to have reversed, hence the name "Reversing Field Effect".
Earths Magnetic Field is passing through the rod and "lighting" up the field imprint left by the Reaction Process.
Northern Hemisphere: In the northern hemisphere the rod all ways reads North Up.
Equator: At the Equator the hole length of the rod reads North when viewed from the East and South when viewed form the West
Southern Hemisphere: In the Southern hemisphere the rod all ways reads South Up.
Rod Reader: There is a lot of information about how the Reactors are working encoded into the rods fields. To study this we built the GEET life Rod Reader, 3 axes magnetic field imaging machine.
