Incredibly strong (neodymium) magnets

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

Shape: round

Size: 25 X 7mm

Quite a strong magnet, there are two versions, both the same except that one is just the magnet and the other includes a threaded stem ('studding') complete with a small nut. The stem is 10mm long, the fitting (diameter) is M4.

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.

Shape: round (pictured)
Size: 8 X 12mm

Small and neat, very powerful for its size, good to keep in your buying bag for going out to auctions and fairs.

Shape:cylindrical (not pictured)
Size: 9 X18mm

The 'long' shape makes it easy to hold, take this one if you can't hold small objects, also just amazing for holding papers onto a fridge, several times the strength of a fridge magnet yet easy to pull off.
