    This is my first post here on thescienceforum. I tried to do my own research but a having a hard time with some of the technical terms.

    I am trying to figure out a methodology to identify a certain piece of metal by its compostion using magnets.

    The metal contains approximately the following parts:

    4.5/50 parts Manganese
    28/50 parts Copper
    17.5/50 parts Silver

    I tried to do some experimentation and here is where I am at. I did not know silver had magnetic properties. The magnet used was a rare earth magnet to test. I believe it was Neodymium. It appears that this type of magnet would repel silver but attract manganese (what I gather from my research). Im not sure what effect the copper has in all of this. The result with this is that it somewhat sticks? I believe the two effects are canceling each other out. I know there are a variety of magnets. I would either like to be able to strongly attract this metal or strongly push it away with this metal.

    Does anyone have any ideas or suggestions?

    Thanks for taking the time to read and respond to my post.

    In the circuitous haze of my mind
    When the metal 'sticks' to the magnet, eddy currents are being generated.

    Of all the wonders in the universe, none is likely more fascinating and complicated than human nature.
