eli5: Why are magnets not generating free energy?

204 views

Me and a few friends started to argue about magnets. Of course we know there are the laws of thermodynamics that basically say you cannot generate energy from nothing.
But what of magnets? If i stick a magnet to the fridge it must be generating at least enough energy to not fall down due to gravity.
Where is this energy coming from? Should it not like run out of energy sometime?

You are mixing 2 things together… Energy and force

If you glue brick to your ceiling, the force of glue supports it… But there is no energy being generated
