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.
How does this compare with our other (standard, iron) magnets?
Strengths
How many sheets of paper* will this magnet hold securely onto a fridge door?
Answers:
- smaller (10X30mm) 75
- larger round (20X30mm) 90
* A4 in size, 90gsm in weight (heavier than standard copy paper).
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...anything (including gold and silver).
Silver is not magnetic, but 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.
Copper is not magnetic, neither is brass (a mixture of copper and zinc) or bronze (a mixture of copper and tin). A magnet is useful because many copper / bronze / brass items are really steel that has been plated and will (in most cases) be magnetic. So if an item is magnetic it cannot be solid copper / bronze / brass. Being magnetic does not prove it's steel, not all steel is magnetic.

QUESTIONS & ANSWERS
Ask a Question-
How much does this product weigh ?
The smaller of the two weighs 190g, the larger weighs 280g.
-
What is the pull on the 30mm x 30mm magnet?
By attaching a nylon bag to a vertical sheet of steel (on a shelving unit) and filling it with weights: 6Kg. However, this method creates a 'lever' which pulls the bag down easily, the actual 'pull' will be greater than this.
You can see the relative strengths of each magnet in the STRENGTH tab of each description, this measure being the number of sheets of 90gsm A4 paper the magnet will hold on a fridge door. By this measure, or weakest iron magnet is 3 and this 30X30 is 90
