Question about magnetic shielding

Click For Summary
The discussion centers on the interaction between repulsing magnets and a piece of metal, questioning whether the repulsion could cancel out attraction and if this could enable a self-driving mechanism. It is clarified that the concept of perpetual motion machines, including magnetic motors, is not permitted in the forum due to its classification as pseudoscience. The thread emphasizes the importance of adhering to established scientific principles and the futility of seeking free energy solutions. Resources are provided for further reading on the topic of perpetual motion. The conversation concludes with a reminder of the forum's rules against discussing such topics.

so i understand that if there's a piece of metal between 2 repulsing magnets, the magnets attract to the metal as well, and the repulsion could cancel out the attraction... right? i mean is this even true.
if not why not...

if it is true, then is it possible to have 2 wheels of repulsing magnets drive itself based on the attraction of the magnet to the piece of metal and the repulsion on the other magnet wheel...
why or why not...

i know I'm like thermodynamically ignorant.. so please educate me...
thanks.

alodia -- we do not discuss perpetual motion machines (PMMs or "magnetic motors") here on the PF. They are on the list of Forbidden Topics in the PF Rules (see Site Info at the top of the page).

Happy holidays folks. So I spent some time over the Thanksgiving holidays and developed a program that renders electric field lines of swiftly moving charges according to the Liénard–Wiechert formula. The program generates static images based on the given trajectory of a charge (or multiple), and the images were compiled into a video that shows the animated field lines for harmonic movement and circular movement of a charge (or two charges). Video: The source code is available here...
