George Green's Magnetic Ring. Free Energy?

Difficulty of realization 7/10

OK, the free energy do not exist, but this experiment has something magical that makes me think of infinite energy.

How do you turn the rotor without a source of energy?

To speed up the disk needs a path to follow of least resistance. I trace the route moving slowly the ring. I pass the energy from my hands to the rotor with the movement of the ring.

Why the rotor rotates?

The particular arrangement of magnets with North pole inside oriented you create a magnetic vortex that has the shape of the figure up. This has discovered an ingenious gentleman named George Green

In the rotor i used one neodymium magnet 30x3mm with hole (North pole upside) in the center with a steel ball 12.5mm and a steel disk to fix the center of rotation. Around the disk 16 neodymium magnets 10x1mm with north pole upside oriented. The plastic disc I found among old CDs

In the ring i used 17 neodymium magnet 20x3mm with north pole inside oriented. To merge the magnets used much adhesive tape to take the ring stiff enough so that it does not bend easily on itself
