Fabulous power
Neodymium-Iron-Boron rare earth magnet: 1/4 sphere... The north and south poles are through an axis of the sphere, as you would expect. Strong enough to hold together *through* your hand. They'll jump 4-5 inches. Don't throw them, they seem to be chrystaline or cast metal, but chromed.
Awesome little things..
I bought the strongest magnets I could find because of frustration with papers I put on the fridge falling down. Be careful what you wish for because these magnets are TOUGH. It takes a lot to get them off of the fridge, but it does what I wanted it to do: keep important papers on the fridge.
They have also been the focus of guest entertainment, as people take turns trying to pry them from the fridge.
I don't recommend them for stainless applainces. We have a traditional white fridge and the magnets scratch the surface, but the scratches can be quickly wiped away...I don't know about stainless appliances though.
