4.) When the disk spins the magnet on the far left or right attracts the magnets on the disk and the disk spins. Then, the magnet is shielded and the other magnet on the other side is available as a magnet and attracts the magnets on the disk. What turn the shield on the magnets is the shield is attached to the disk and spins when the disk spins.

The only safe way to do this is to select a wire such that its resistance is high enough to limit the battery current to a safe level. To begin, you need to read the battery''s datasheet to determine what that safe current level might be.

Why can''t we harness the energy stored in magnets? :
Magnets are batteries. Magnets are not batteries, but I completely understand the reason it seems that way. While it is true that we must spend energy to orient the magnetic domains to create a magnet that is useful to us, once that work is done the energy is converted to heat, it is not stored in the material like a spring.
