DYI Making Poly-Magnets CMR
Here one will find my research on what is known as a Poly-magnet. Correlated Magnetics Research was the first to show these type of magnets.
I was introduced to theses magnets by Jason verbelli. Jason has been trying to replicate theses magnets in his spare time. As i was building the 10,000 Joule capacitor bank I offered to help try to create theses magnets for him by discharging the Cap bank in to coils. Jason sent me some blank non magnetized neodymium "blanks" to try out. It took me a while to get to the testing but once i did i was pleasantly surprised that it worked. At least my first tries. There is more to do, but a lot here already. Yes, I only got one "pixel" done on a fully magnetized magnet. This is also a patented technology, but I'm just proving that a lot of "complex" things can be done with enough effort, at home in the "LAB" with out complex or expensive system.
Here is a nice video I put together to show the first test results.
Here are some photos of the CMR magnets along my first attempts:
Theses are the " hoverfield" magnets from CMR. One can see the " pixels" ( thanks Jason For These!!)
This is magnetic viewing film:
This is FerroFluid :
here is the coil i used, this was a unit out of a dot matrix printer:
Each pole was connected to give a reverse polarity.. I only used 8 of the 9 coils. connected in parallel.
after pumping 10,000J in to the coil across a non magnetized "blank" neodymium disk here was the outcome:
In this photo there are strange lines and such, This was some of the lines left by the wire that was ran in sire the coil Assembly.
This is the back side of the magnet. clearly there is some N and S fields on there.
I then took a larger 3/4" magnet and " erased" the stuff that was not permanent.
Next up was to try a magnet that was already magnetized to see if we could " flip" a "pixel" on to it. The only magnet had at the time was a ring magnet. here is the coil used. it also came out of a dot matrix printer.
Before:
After:
Here is the outcome:
Yep! That's a magnetic pixel alright. Its not a " dead spot" this i tested and clearly showed in the video.
Next up is to make Manny "pixels" and see if we can get the effect we are looking for!
