Great work VK!!

This shows ( at least in appearance) to verify the working principal.

looking forward to further experiments from you on this subject.
mechanical linkage to synchronize the actions would be advantageous.
so you're not doing it by hand.

good job,

Sm0ky2, pirate88179, thanks for your comments.  Making mechanical transmission is a difficult task which requires some acuurate
fabrication work and it is beyond my scope.
 
Meanwhile for anybody trying that experiment, my suggestion is, keep the moving magnet as weak as possible and make the fixed magnet very strong so that when weak magnet comes near the fixed repelling magnet, there will not be much variation in density of flux with respect to the shield.  You will get the required effective force between magnets because magnetic force depends on product of strength of both poles.
 
If moving magnet is stronger, then it causes greater variation in flux density with respect to the shield which in turn tries to hold the shield in the region of stronger flux density and you will experience a strong force while moving the shield.

 

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.

This explanation  is very well applicable for a normal mechanical pendulum executing simple hormonic motion. The magnetic pendulum used in the experiment doesnot work like a simple pendulum.  Its amplitude simply depends on the repulsive force experienced from fixed magnet.  I have made it like pendulum because building piston and flywheel arrangement is difficult for me.  As you can see from the video, its amplitude rises within 2-3 movements of the shield because when pendulum comes closer and closer to the fixed magnet,  it experiences greater and greater force since magnetic force is inversely proportional to square of the distance between poles and directly proportionalto product of strength of poles.

You cannot continuously extract any more energy than you are continuously applying with your hand or the resonance and the amplitude will collapse.

Amplitude of pendulum is collapsing in that experiment is only because of miss-timing. When pendulum moves towards fixed magnet, it should not experience repelling force (shield should cover the fixed magnet). If it experiences repelling force then its momentum and energy will be damped and it comes to halt. Shield should open only when pendulum comes to a predetermined closer position. Since I am operating the shield by hand and pendulum is moving very fast, I am unable to corrrectly time the movement of shield hence the pendulum is stopping.
 

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.

This can be easily verified by keeping the magnet vertical and keeping a weight on shield. When shield moves down magnet deflects (repells) the pendulum mass (hence weight) to some height above its mean position.  By comparing the weight and height of deflection of pendulum  with weight and height of shield movement you can easily know the input and output energy in each cycle without considering power because time remains the same.

 

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.

Even if the shield is attracted strongly towards the magnet, it can be moved easily over the magnet by using steel ball roller since ball is held to the magnet by point contact. Frictional force depends on area of contact and also coefficient of friction between the contact surfaces.  You will experience it if you conduct the experiment.
 
Eddy currents and joule heating lossess are negligible at lower speeds and it is possible to operate this system at lower speeds and get higher energy output.
 
Thanks for applying thought on this experiment.

This principle isn't sustainable without input work.
The pendulum magnet approach because it is attracted to the steel. So therfor you must spend the same amount of force to remove (Force * remove = energy) the steel so the stator magnet can have more influence on the pendulum magnet. The energy causing the pendulum magnet and the steel plate to move is exact equal and opposite. No excess energy. It's not an assumption, but I know this from measuring experiments - which also happens to be correct in simulations as well.

Observe the video closely.  Pendulum is not attracted by the shield.  When you cover the fixed magnet with shield, it (shield) cuts off the repelling flux with respect to pendulum hence the pendulum falls towards its mean position by gravity and moves further towards fixed magnet due to its momentum. At this point if shield is moved exposing the fixed magnet, pendulum will again get repelled away.
 
I have suggested the following points to eliminate the same problem :

1) Keep the fixed magnet very strong and moving magnet considerably weak because a weak magnet cannot get attracted
   towards shield from far distance.
 
2) Maintain some minimum distance betwee fixed magnet and pendulum magnet because when weak pendulummagnet comes closer
    to the fixed magnet (at maintained minimum distance)  it will not create much change in density of flux with  respect to shield 
    because  shield will be moving on a strong magnet and in a plane parallel to the pole of magnet.
