I let two magnets attract from a distance and when they hit they both broke a piece off of each-other. Why did the magnets damage each-other when they collided and is it possible to put the broken magnets back together? I have powdered the small piece and keep the powdered part in a bag

    $\begingroup$ Are they ceramic magnets? It may be hard to repair them, depending on the direction of the break relative to the north-south axis of the magnet. Usually, when ceramic magnets break the 2 pieces repel if you try to put them back together. $\endgroup$

  • $\begingroup$ yes they are but they don't since I have a mold an powdered the small fragments $\endgroup$ Feb 12 '19 at 19:34
  • $\begingroup$ The powdered fragments will not be usable in repairing your magnets because you won't be able to re-assemble them with their original orientation. However, they might be useful in other experiments. $\endgroup$

most commercial magnet materials are quite brittle, and smacking the together will often cause them to fracture. you can indeed glue them together. Try some cyanoacrylate ("crazy glue").
