Rubber type fridge magnets are strange, alot of opposite poles all on the same face. Sort of like pin heads poked in to fill the surface and any head could be either S or N poles. The poles are smaller than pin heads of course, probably a magnetic dust randomly molded into a rubber mat or something.
As said, basically you can get anything the way you want to pay for. Spheres, little round magnet balls??? Still wondering what I could use those for.
