Product Description:
Rare earth magnets are the strongest type of permanent magnet currently made. They are amazingly powerful for their size and have innumerable uses. These block magnets are 0.750 inch (19.1mm) long, 0.750 inch (19.1mm) wide and 0.125 inch (3.2mm) thick. They are magnetized through the thickness. They are composed of grade 40 neodymium iron boron magnetic material and are plated in nickel-copper-nickel for a shiny corrosion resistant finish. Their individual pull force is approximately 9.1 lbs. Maximum working temperature is 176 F (80 C). Magnets may chip and crack if allowed to snap together
Customer Reviews
Average Rating: 
Rating: - Very strong magnets
These are, as it says on the tin, very strong magnets. It's quite hard to separate them when they stick together, and surprisingly easy to hurt yourself with them, so be careful.
I don't know what I'm going to do with them, but I like them anyway.
Rating: - Caution - these magnets are awesome (but strong)!
These are "very" strong magnets!
If you are using them for science projects (e.g. building hydro electric generator) these are the ones for you.
But they are not easy to separate and they can really pinch someone if they snap together unexpectedly.
Fun but keep from young chidren!
