    Why should it be about making prints?

    I have a suggestion.

    Go out and buy the biggest and strongest magnet you can and then try to drag some Ferric or Ferrous salt out of solution with it. If you do, then patent it and write it up for your Nobel Prize.

    Curses. I was expecting something novel from this thread.
    Using film since before it was hip.

    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
    ask me how ..

    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?

    But if you add some imported Parmesan Cheese, viola! It sticks to a magnet!
    Develop, stop, fix.... wait.... where's my film?

    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!

    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.

    Some Stainless Steel is non-magnetic as well and it is basically iron!

    Nickel is magnetic, and nickel isn't iron.

    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?
