The magnets are made of flexible magnetic foil

so that there are no small stones or dirt that can create distance and cause the magnet to fall off

as these neodymium magnets cannot withstand high speed collision with other magnets

desto svagere vil magnetismen blive

Metalkugler Ø20 mm. (10-pak) Tier1 The magnets are made ofLarge, round metal balls in a bag of 10. The metal balls are magnetic but are not magnets themselves. They are used together with magnets as "links" or for when you want to experiment with magnetism e. g. make a gauss gun. These are not magnets! The metal balls are also called metal spheres. You can do some pretty cool things when you put bar magnets along with these steel balls. Made from high carbon chromium steel containing 1% carbon and 0. 5%1.
