Ferrocell Q&A - FAQ's
Q: Why is there a spot in the cell that doesn’t go away after I remove the magnet?
A: A powerful magnet was sitting in one location on the glass for too long.
Prolonged exposure to high intensity fields will ‘burn’ the nanoparticles.
Use non-ferrous (plastic, wood, etc) spacers between the magnet and cell surface to
prevent this from happening.
Your cell will need to be returned to Ferrocell for repair or replacement.
Q: What are the tiny speckles inside the glass when the LED’s are on?
A: Those are dust particles. Even with air purifiers, ionic filters and continuous
cleaning practices, microscopic dust finds it’s way in and is highly reflective.
Unfortunately, I can’t afford a ‘clean room’ at the level and pace I make these cells.
Dust is annoying, but I find they provide ‘markers’ to use as reference points.
If you think there is an over-abundance of dust in your cell, please contact me
about a re-build or replacement.
Q: Why doesn't my cell show the lines as bright and clear as the pix on the website?
A: There are a few things to check: 1> View in a dark room. Turn off the lights and close the curtains or blinds.
2> Remove the bottom cover if you are using a demonstration unit that comes with one. It's mainly a dust cover
and should be removed for viewing. 3> Provide a black background, either with paper or cloth under or behind
the cell. Distance from the background is proportional to cell diameter. ie, a 62mm cell has a 'dark focus' about
60mm from the background. Likewise, a 100mm cell should be spaced 100mm away from the black background
for optimum results. For maximum brightness and contrast, make a 'Black Hole' (click for link)
Q: What is the maximum magnetic strength (Gauss or Tesla) I can apply to the
surface of a cell?
A: This factor is dependent on glass thickness, temperature, magnet surface area and time.
A 2 mm thick Ferrocell begins to saturate and display with as little as 1000
Gauss (.1T) from a small 10 mm (3/8”) neo cube at room temperature (22C or 72F).
4 & 4.5 mm cells will saturate around 2500 Gauss from a 12.5 mm (1/2”) cube, while the 12 mm cells
require 6000 or more from at least a 19 mm (3/4”) cube; all within a 30 second resolving period.
Stronger fields or longer viewing times will require the use of spacers between the cell and magnet(s).
This is especially true for large magnetic surfaces such as ring or wide block magnets. Their flux is
highly concentrated in certain areas and you risk damaging the cell. Use care when experimenting
with hybrid cells, one side will be much more sensitive to magnets than the other side. It's easy to
forget and 'fry' a cell. I'm not advocating carelessness, but they do have a 2 year warranty.
Q: I'm confused. Why doesn't the Ferrocell show the same geometry as iron filings or FEMM plots?
A: There is much debate and speculation on this issue and I imagine it will be a long time before we have a
100% solid answer. For one thing, iron filings are ferromagnetic. They become little magnets themselves when
exposed to a magnetic field and most of the computer simulations are made from such ancient studies.
We see their maximum potential as they align with the field and each other. However, the magnetite
nanoparticles inside the cell are paramagnetic (actually, super-paramagnetic) and can not be magnetized
in the same manner as expressed by Classical Physics. They tend to 'flutter about' without a
polarization until, over time they form into microscopic 'chains'. These chains become susceptible to the
influence of a magnetic field when they reach domain size. The best way I can describe a Ferrocell is
to imagine a diffraction grating or nano-scale periodic surface that is dynamic instead of fixed on a
substrate. The same laws of diffraction apply, only the cell has 4 more degrees of freedom than a substrate-
based lens or a refractive surface. The particles are always moving even when the magnetic field is stationary!
I state until proven otherwise, we are seeing the lowest potential of the field, which is the lowest point a super-
paramagnetic particle can reach. This is a null region, or the Bloch Wall.

Q: Why does my new LED ring looks like it’s used or scratched?
A: The housings and other plastic parts are made on 3-D printers and not injection-molded like most
other plastic products you see. One of the drawbacks of using this low-cost process for making these units
is ‘fly’. These are little ‘hairs’ of plastic that occasionally stick to different areas during the printing process.
I’ll admit they make the finish look bad, but switching to 3-D printers has allowed me to lower the costs
almost 50% since 2013. If you are looking to pay more for a 1st class unit, I’ll gladly make arrangements
with my machinist. He hasn’t heard from me since I got the printers and would be happy for the work!
Q: I see you are continuously updating your formula and demonstration units.
Can I upgrade what I bought earlier?
A: Yes, by all means. You’re a member of a curious group of people who have experienced a phenomenon
no one else has ever witnessed. We want your enthusiasm for this new technology to continue !!!
I’m always trying to make these things better. Contact me any time for upgrade information and pricing.
Q: The power adapter supplied with my demonstration unit does not fit the power outlet in my country.
What can I do?
A: All of the Ferrocell demonstration units operate on 12 Volts DC at less than 1 Amp. You can substitute
any locally available 12 Volt adapter that has a 5mm output plug. Observe plug polarity: center is positive
(+) and outer sleeve is negative (–). If you must use another adapter, contact me for a partial refund on your
Q: I want to experiment with a Ferrocell, but I can’t afford one. I’m a student and funds are limited.
A: Ferrocells can be purchased at a discount or obtained without charge if you are attending a college or
university and your field of study includes optics, magnetics, nanotech or quantum electrodynamics.
Collaboration is required to get these discounts, which may prove difficult if your institution is working
in areas that require NDA’s or are conducting confidential research. However, I will do my best to
accommodate your needs. Also, used and blemished cells are often available at huge discounted prices.

Q: Have a different question?
A: Send an email to: firstname.lastname@example.org and ask me about it.
