  1. Gold and silver are both non-magnetic, so if the magnet sticks to the coin, it proves that the material that the coin is made from is magnetic; and cannot therefore be real gold or silver.

  2. Under the influence of a strong Neodymium magnet, the structure of the silver/gold electrons become affected and the silver/gold coin becomes very slightly magnetic, which is why the magnet slowly slides down the coin.
    When the magnet is taken away, the silver/gold reverts to it's original (non-magnetic) state.

  3. The magnet can be obtained from the website link under the video above.

    Neodymium magnets are made from an alloy of neodymium, iron, and boron, and have replaced other types of magnet in the many applications in modern products that require strong permanent magnets such as it is used for here.

  4. The magnet would slide down the GML slightly slower than the GAE due to the GML being the purer of the 2 at .9999

  5. A smaller magnet might not affect the electrons in a 1oz silver coin enough for the magnet to slide down the coin slowly – it might slide straight off. This is why we use a 10mm magnet at Silver-Dollar.co.uk

    A 6mm magnet would be more suitable for smaller coins.

  6. I don't understand. I would expect the silver eagle test to have the fastest slide because of the minimal ferrous metal. I would expect to have the genuine crown coin to have the second fastest slide because it is not as pure as the us coin and the fakes to be the slowest because of the ferrous materials. This is not the case in this test, there doesn't appear to be any consistency. Can you explain why? Thank you.
