Curses. I was expecting something novel from this thread.
the heck with a rare earth or electro magnet
throw an electric charge through the cyanotype
while you print it and its subject and see if you can get a cyanokirilian print ;)
What about a strong, alternating magnetic field such as that which might be generated by a rotating drum with magnets fixed to its surface in alternate N-S-N-S fashion?
You can use this technique to REPEL copper, aluminum and other non-ferromagnetic metals. It's the eddy currents which cause the repulsion.
This is how trash recycling machines separate ferromagnetic metals, non-ferromagnetic metals and paper/plastic/trash. First, they use a magnet to suck up the steel and iron. Then they use a rotating drum magnet to repel the copper, aluminum, etc. into a chute.
Would this technique work in our case?
NO Tk. I tried it with a vintage Parmegiano Reggiano and it did not work! Sorry.
I am working on a Molle to see if it will work! :D
It is important not to confuse atoms with ions. Their magnetic properties are very different.
There are three types of magnetic susceptability; paramagnetism, diamagnetism, and ferromagnetism. The first two are extremely small and need special equipment to be measured. Most materials exhibit either paramagnetism or diamagnetism. A very few substances like iron exhibit ferromagnetism.
Can light or radiation have an effect on ferromagnetism, to a degree that it could be utilized in some fashion to make an image? I'm kind of thinking along the lines of Xerox; where a charged plate of selenium loses that charge with light exposure. Any kind of similar phenomenon we can exploit with magnetism?
