So i got this email from All Electronics which had some interesting magnets in them. I've never heard of Samarium Cobalt magnets before (how do they work???). They appear to be about 5mm. Think they are better then the neodymium ones we normally use?

A samarium–cobalt magnet, a type of rare earth magnet, is a strong permanent magnet made of an alloy of samarium and cobalt. They were developed in the early 1970s.

They are generally the second-strongest type of magnet made, less strong than neodymium magnets, but have higher temperature ratings and higher coercivity.

This from a chemistry text on them. I borrowed it from a friend whose thesis was on rare earth magnetism.

Thanks! Now I know, and...
