What"s the differance between rare earth magnet and other magnets??

Rare-earth magnets are strong permanent magnets made from alloys of rare earth elements. There are two types: neodymium magnets and samarium-cobalt magnets. Rare earth magnets are extremely brittle and also vulnerable to corrosion, so they are usually plated or coated to protect them from breaking and chipping.

The term "rare earth" can be misleading as these metals are not particularly rare or precious; they are about as abundant as tin or lead.

OK guys thank you for the fast responce.   
So rare earth magnets are stronger then regular iron based magnets.so beware of pinching between two of them.   check and double check.....

Thinking of placing one earth magnet on the handle end of my digger to pick out iron and whatever else sticks.

"also good in the bottom of a water scoop"


Both very common and very useful applications.        Used the first one a whole lot this past weekend (only problem was the ground was so lousy with iron, that no matter where I put the think, the magnet came up with soil.)
