Magnetic field compression experiment using stack of magnets

A stack of magnets fixed on a wheel is repelled by half stack of magnets fixed on the table.  When magnetic field of fixed magnet is compressed by another stack of magnets,  the wheel magnet stack is attracted to it and gets repelled when compression is removed.   The wheel rotates continuously if oscillations of compression is correctly timed with rotation of wheel.

A crank would be more efficient than magnets to rotate this hand powered motor.   :)

Even if you tilt the table, the wheel will rotate and it will be more efficient than using a 'crank'.   It is just an experiment to show that magnetic field compression can be made to rotate a wheel.  Please read the topic.

At least in ideal case, you don't need more energy to rotate the wheel when you tilt the table. The additional energy it requires to go upwards was gained before when going downwards. The only energy you need is to overcome friction losses from air and bearing.

Where are your measurements that prove it?!
A crank means an efficiency close to 100% because it transmits mechanical energy without loss except for low friction.
With moving magnets you have eddy currents.

This is well known and already used in the magnetic gear industry.
A field is only a set of scalars defining the intensity of the field at each point of space. "Field compression" is just a way of saying it, you can't be fooled by it. The only fact is a change in the topology of the field, and therefore in the set of scalars.
