4 Russian experiments

Experiments that demonstrate the full force of our super magnets
Author: Aleksei Kokorev, Tver, Russian Federation
After his experiment with the floating compass, Aleksei from Russia sends us four more of his experiments that demonstrate the full force of our super magnets:

Small, but powerful: The disc magnet S-20-10-N can pull up a medium dumbbell or even a weight of 8 kg! The scale proves it: No trick!

Here, Aleksei demonstrates that our magnets keep the promise that we make: A cube magnet W-12-N can easily hold a dumbbell of almost 5 kg.
Note from the supermagnete team: It is risky to hang up heavy objects with magnets. Please consider our warnings under "heavy objects."

This experiment shows clearly how a super magnet influences a compass much more than a normal ferromagnet. Even at a very high distance to the magnet, the needle starts moving.
But not only that: Super magnets can even change the polarity of a ferromagnet. You can see that when you watch where the compass needle points to before and after the ferromagnet had contact with the super magnet.

Finally, this experiment shows that a SuperMagnet can massively demagnetise a normal ferromagnet, so it comes off a magnetic board - almost by itself.
In a next step, the SuperMagnet can give the normal magnet power again, so it sticks to the magnetic board again.
