How To Test Silver or Gold | Neodymium Rare Earth Magnets

December 10, 2012 by  
Filed under Gold Coins


This is a brief example of how to use a Neodymium rare earth magnet to test if an item is solid silver. It is meant to be one of a number of tests to verify precious metal contents, but it is an inexpensive and effective way to see if the coins you are buying are real silver. I have a few for sale on ebay. User id: brysco I hope you enjoy the video! *You should always wear gloves when working with silver; however, these are some of my silver coins that I don’t mind tarnishing

    the property that is displayed by the magnet on the silver coin is diamagnetism. diamagnetism is when a non-magnetically charged material repels the magnet. it travels down the coin slowly because of this.

    the magnet slid off first coin and it was silver and on the mexican coin it slid off the same and u go ” o its not silver” whats the point of test if they both slide off and only one silver dmas

    First time i’ve ever seen this test. You can get Neodymium Magnets from ScienceKitStore. com . I got them for a Guass Rifle but now I can test my coins!

    Then you have to judge based on weight and size.

  5. TheSteveo613 says:

    What if the coin is copper and coated in silver? then what. The reason your magnet slowes is due to len’z law. your inducing a current but the resistivity of copper and silver are almost the same so also is the conductivity. this test would fail in such a case. If your going to buy silver I would say use Archimedes’ Principle. SG of metals will tell exactly what percent of silver your dealing with.

    Innversion happens because of the camera, if you look at the silver eagle, you’ll notice it is inverted as well.

  7. TheEpicPoker says:

    The Morgan Dollar is not real… On the real coins, Lady Liberty is facing the left. It might be a reproduction silver coin?

  8. John Pietruk says:

    cool

  9. iBitcoin says:

    That’s a really nice steel cent, and Morgan dollar for that matter
