Interrupting magnetic field to cause Gravity fall

[Rapadura]

Jerry, I watched yout video again (MagneticShieldMovie.wmv) and that inspired me with an idea to try to get us back to the good old way of trying to make a perpetual mobile without coils and electromagnets, just with permanent magnets and gravity...

I think I had an idea of how we can make a magnetic shield that rolls down to the right place at the right time ...

If the ball can go up on a inclined upper path... And this video shows it is posible:

If the ball goes up on a inclined upper path, it can push a small part that will release the sliding of the magnetic shield in the proper moment.

The image bellow is a side view of how I imagine the small part could be constructed, in order to drop the shielding at the right moment.

The last magnet is just above point 1 of the small part, so the ball will stop right where point 1 of the small part is, pushing point 1 to inside the equipment, and point 2 will also be pushed to inside. This will release the descent of the magnetic shielding to the appropriate location, sliding, driven by gravity.

If the shielding can slide until between the ball and the last magnet, the ball will be pulled down by gravity.

If this works, we will only need to imagine a mechanism to move the shielding back to its original place after its work is finished.

And I guess if the ball is heavier than the plate that will be used as shielding, and the final height from where the ball drops is a great enough height, it will not be difficult to create a purely mechanical system to harness the ball's fall to move the shield back to its place, just sliding up...
