2. The Invention
The Ferrocell® was conceived while I was searching for a quick and easy way to observe the magnetic component of a wireless power signal back in My knowledge and experience with Ferrohydrodynamic fluids gave rise to the idea that a magnetic field might be observed by passing light through an ultra-thin transparent layer of Ferrofluid, sandwiched between two sheets of glass and activated with magnetism.
My early experiments proved the Ferrocell® was indeed a simple method in which to visualize the lowest potential of a magnetic field and I applied for a patent in 2006 (issued 2012).

I was quite fascinated by the results of this experiment.
A detailed examination convinced me we were seeing an unusual phenomenon.

7. 5 years later…
I returned to my experiments, this time replacing static magnetic fields with slow moving electromagnetic fields. (slow enough so our eyes can detect movements). My challenge was to make this tiny event macro-sized for us to see with the naked eye.
So, I create a sequence of four electromagnetic pulses 90 degrees apart and feed them into a high power, wide bandwidth audio amplifier.
Next, I actuate four coils set at right angles to each other with the amplified signals. Each ‘deflection’ electromagnet has a single pole placed on the outer edges of a Ferrocell®.
Light from a 5mW red laser passes through the activated Ferrocell® where the beam becomes scattered into the lowest potential of the applied magnetic field.
Beam rotation occurs when the four electromagnetic deflection fields are pulsed in a 90 degree sequence of the same polarity and are equally balanced in strength. Light variations from the fiber optic cable ends are detected by phototransistors in the opto- sensor unit. These signals are amplified, conditioned and routed to four indicator LED’s plus four outputs to provide signals to drive another stage or an oscilloscope.
