Don’t play with them.
Are your magnets losing their super powers? If yes, it is probably because you are playing with them (we all do 🙂 ). We need to know that a magnet is made out of lots and lots of little magnets called electrons. When they stand (spin) in the same direction they are stronger which results in what we call magnetic force. When we apply some physical or thermal energy to them they start to lose same direction.
At 80°C (176°F) magnets start losing their super powers.
So next time you want to play with them, remember that every action has a reaction.
I promise no spam. 😉
