Neodymium

Silver is not magnetic. However it is 'diamagnetic' - a sliding magnet sets up an 'electrical field' which you can detect with suitable magnets.

These magnets are 'suitable' because of their size and power.

Read all about it!.

IMPORTANT

Copper reacts the same way as silver (though the effect isn't as strong), so this test will not tell you if you have a copper coin plated with silver. YOU STILL NEED A SILVER TESTER to be certain.


This is a very low value item. We have a minimum order charge of £7.50 (£6.25 + VAT). Is this the only item you require? You may wish to buy more than one, or add some other items to the order.

Quantity:  

{Summary}

Limited quantity, once these are sold there are no more.

Material: neodymium, excepitonally powerful for the size.

Choice of three sizes.

How does this compare with our other (standard, iron) magnets?

{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.

{Variation on 3X4X20}

We have several thousand of these and have discovered that not all of the little rectangular magnets are exactly the same size.

If you just want a tiny very powerful magnet, this will make no difference.

If the exact size is important to you (e.g. you are buying to fit an exact space):

3 X 4 X 20mm, we have enough to last until about the end of February 2020 [these have now all gone]
2 X 4 X 20mm, we have enough to last until about the end of Marchl 2020
2 X 5 X 20mm, we have enough to last until about 2030.

{Summary}

Material: neodymium, exceptionally powerful.

Choice of three sizes. Although we sell these for testing metals, the cylindrical shapes are particularly good as fridge magnets, they are powerful enough to hold several sheets of paper.

{Summary}

Limited quantity, once these are sold there are no more.

Material: neodymium, exceptionally powerful, these large sizes must be treated with extreme caution, any fingers caught between two of these will be completely crushed. Treated with care, these are just amazing

Choice of two sizes.
