Magnetic Engine Video

There is enough drag just by introducing magnets, Don't add to it with mechanical( physical) connections.
It's like a flow that intensifies , control the flow , start small ,increase, then release.
If you can loop a mag track, is that perpetual motion? The track will wear out, and how long will the magnet last?

There is no drag in the setup because shield is moving parallel to the pole on the surface of pole experiencing uniform flux throughout its path. There is only frictional force between moving ball and magnet's surface. This frictional force is very less
because of 'point contact' of ball with the magnet which can be further reduced by lubricating the surface.

The question here is not really perpetual motion but it is about overunity.  Is output enrgy more than supplied input energy?
To know the answer we have to make proper measurements.

If you conduct this experiment you will feel that you will not experience much force on your hand but the oscillating magnet
developes considerable energy due to repulsion.

I am very impressed with your experiment.  Normally, when I see "Mr Hand" come into play, I dismiss whatever is being attempted to be shown.  However, in your video, it makes one think that possibly  (I said possibly) one might be able to create a device that slides that plate in and out of the field in correct timing.  Maybe there is something here, maybe not but, your video really makes one think about the possibilities.

I am glad I was able to watch it.

You are putting in a small amount of mechanical energy each cycle with your hand. When properly timed to the pendulum swing, some of this energy is stored in the mechanical resonance of the system and the amplitude of the swing can build up. You cannot continuously extract any more energy than you are continuously applying with your hand or the resonance and the amplitude will collapse. You are also experiencing losses due to friction and eddy current heating in the moving "shield", so with each cycle, the actual energy delivered to the pendulum is less than the energy you are applying with your hand during each cycle. This means that the system cannot be self-looped with no outside source of energy aiding the looping. It is true that you can extract all the energy stored in the pendulum at once, and this will be higher than the energy of a single input cycle of the hand moving the shield. Power is not energy and especially, peak power is not energy.

The general problem with magnetic "shields" is that they are strongly attracted to the magnet being "shielded". This means it requires work to move the shield into and out of the shielding position. Since the shields are also almost always metallic and electrical conductors, they will experience eddy currents and energy loss due to Joule heating with every movement of the shield.
