I once read in school that magnetism comes out of one side of a magnet, goes around, and then goes back into the other side of the magnet. Like making a circle.
Do we know HOW magnetism is moving out, and in, the magnet?
What is making the - energy? - that makes magnetism, move?
I think of energy stored in a battery. But in a battery, the energy goes out, does not come back to the battery.

What you are describing is a magnetic field. I think it takes energy to magnetize an object in the first place to turn it into a magnet. Then it is a source of potential energy that can be used up over time. I think that magnets do lose their magnetism over time in the same way as a battery loses charge.
