Introduction: 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.

Step 1: How It Work

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

Step 2: How to Make Rotor

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

Step 3: How to Make the Ring

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

Not Free Energy. You need to apply the input by moving.

I had an idea similar to this! It seems to work with the same principle.

Well, realize it and make an instructable :-)

To the author, attach a slightly magnetized circular plate with olive oil to the steel ball and youll get better rotation:) i saw someone put a track on the bottom so it followed in a circle with the rotor on a tensile spring in a looped fashion above it.. Ran for quite awhile

Good suggestion, thanks :-)

Oh, you're no fun, Omnivent.

Gets close to infinite energy, only bound by the size of the plate.
This demonstrates other parts of physics, like angular momentum.

And talk to the school board about what should be taught.
Until they get that right, I'd rather see creative illusions
and things that encourage kids to experiment.
