Neodymium magnets
These are also called Neo magnets, Rare Earth Magnets, Neodymium Iron Boron magnets or NdFeB magnets.
They are very strong for their size so they are ideal for magnetic therapy. Stronger magnetic dots (or bandages) are also made from this material.
They last very well - they should last you a lifetime if you look after them.
Don't get them too hot - heat will demagnetize magnets made of this material. And don't drop them if you can help it. The shock could demagnetize and/or break them.
Their disadvantage is that they rust very easily - and who wants rust all over them. So for magnetic therapy they are coated. The better ones are coated in 24 carat gold and the cheaper ones are coated in paint or maybe copper - which can also stain one's skin but is likely good for you when it does so.
Whateverer they are coated with, it won't make any difference to how strong they are as magnets. The strength of the magnet is a function of the material it is made from and it's size.
2 Neo magnets the same size are the same strength.
The reason why some suppliers will say their magnets are 3750 gauss and other suppliers will say that their magnets are 2500 gauss is because the first supplier is talking about how strong the magnet is inside at it's centrepoint, and the second supplier is talking about how strong it is at it's surface. One could wish that there was a standard here!
