Uses for testing

Gold and silver are not magnetic. So when you are presented with dozens of items to test, save time by picking out all the items that are magnetic.

This does NOT mean that there are special magnets for testing gold and silver. If an item is NOT magnetic, it could be any one of hundreds of metals (including gold and silver).

Silver is strongly 'diamagnetic'. If you slide an appropriate magnet down a flat silver surface (e.g. a coin) it will move slowly instead of 'falling off'. Copper is slightly diamagnetic. See our 'magnets for silver testing' - a set of 3 magnet, a sample copper coin and instructions.

Copper is not magnetic, neither is brass (a mixture of copper and zinc) or bronze (a mixture of copper and mostly tin). A magnet is useful because many copper / bronze / brass items are really steel that has been plated and will (in most cases) be very magnetic. As with gold and silver: if an item is magnetic it is not solid copper / bronze / brass.

Samples and Wholesale

Not sure which magnet to buy? We have a bargain sample pack of nine different magnets (both iron and neodymium), click here.

For 'standard' bulk prices the price automatically gets lower the more you order (click on "View Quantity Pricing"), however we have these in packs of 1000, special wholesale price 4p + VAT each = of £48.00 per bag, please email, we will send you an invoice.

These are good if you manufacture small fridge magnets.
