Perpetual motion made simple.
Here,
Better as this I cant do
The top magnet inducts a field into the strip. The strip then repels the magnet below it.
Thus the strip is lifted as a result of the magnet above it but it's loss in weight is not suspended from it.
The more magnetic flux we pump into a ferromagnetic object the more it will repel and attract other magnetic objects.
The strip as illustrated is lifted only partially as a result of the attraction. The majority of it's lift is caused by the magnet underneath it.
no really!

And how does this cute little animation with weak narrative indicate perpetual motion? Perpetual motion would be easy if one could build a lossless system. So far nobody has done so. Of course, any attempt to extract energy would bring it to a stop in any case.

The pushing force grows with the flux
- The top magnet inducts a field into the strip.
- The strip then repels the magnet below it.
EXAMPLE:
The magnet at the top suffers 1 newton in attraction.
This means the iron profile is pulled upwards with a force of 1 newton.
The pushing force from underneath grows with the flux in the strip.
More flux in the strip = more repulsion from below.
The increased repulsion from below does not reflect back onto the top magnet.
The top magnet only suffers 1 newton and nothing more.
