Usually surprise is an issue--they can jump out of your hands and snap together from a surprising distance before you realize what is happening. They are strong enough that they can fly into each other or to a piece of iron or steel with such velocity that they can break and send sharp 'shrapnel' flying about!

30x10x5 mm (N52) Neodymium Magnet. Neodymium is about as common as tin or lead. There are two types of “Rare Earth Magnets” SMCO (Samarium-Cobalt) and Neodymium. Neodymium are the magnetically stronger and cheaper of the two but are more susceptible to oxidation, this is why they are protected by Nickel plating.
