Perpetual diamagnetic liquid

[profitis]

Vidar:'The liquid experiment will not work, because wether the field is used as a medium to do work, or the field itself doing the work, does not matter. The loop is closed so in any possible way you look at it, the experiment is depending on what happens anywhere in the loop.'

I wonder what effect dia-magnetic repulsion will have on the vapour-pressure(surface tension) of the liquid? If it has effect then we might get cyclic liquid-vapour movements

There are some obvious flaws in your logic here....   
The magnetic attraction between the magnet and steel, creates an opposing FORCE, imparted onto both the iron AND the magnet.
This force will act against the rotation of the magnet (even if it is not strong enough to fully lift the iron), thus slowing the magnet down, and decreasing the energy in the system.

The attraction between the iron and the magnet is also accelerating the magnet as it approach the iron. Just as much as the same attraction resist the magnet to continue after passing the iron. So there is no slowing down (Assuming there is no mechanical loss in the system).

The motion of the iron has nothing to do with the energy causing the magnet to spin. This loss of energy is directly tied to both the forces of magnetic attraction (induction in the iron), and the force of gravity keeping the iron on the ground.

The movement of the iron has nothing to do with the energy causing the magnet to spin. You're right, but that was not my claim.
The movement in the iron caused by the passing magnet, will cause the pendulum to slow down. Inertia of the iron will force the iron to continue in the same direction as it initialy was pulled into by the magnet. So when the magnet has passed, or on its way to do so, the iron that is still moving away (A tiny bit) from the magnet will slow the magnet down. The iron will eventually turn back, but too late due to its inetria. This is the reason why the pendulum slows down when the iron is allowed to move due to magnetic attraction.

Gravity, being only a force, takes energy out of systems all the time.
For example: take a model rocket engine, when you ignite the fuel, a calculable amount of energy is released, causing a propulsion force.
if this rocket is attached to something too heavy for it to lift, this energy is still dispensed, however, the object never moves.

You're right about the rocket. The rocket burns fuel, but that energy is solely loss if the rocket cannot accelerate away from the force of gravity. However, the energy in the rockets body is zero.
In a sinusodial function, like what you find in a pendulum, gravity isn't causing the pendulum to stop. These functions contains only reactive power. Reactive power poses no load in the system, and cannot do work. Thus it cannot resist the pendulum from continue forever in the field of gravity (assuming there is no friction).

the liquid will be repelled from entering the top of the tube, causing a "gap" where the magnetic field is, and thus no motion of liquid, without removing the magnets, then re-inserting them into place, in a switching action. Or some equivalent.

If it was that simple. Using electromagnets would make that easy, but it would require energy - just as much energy you need to remove and re-insert the magnet.

I believe that the vapour, which is built up by the same type of molecules as the liquid, would be repelled by the magnet too.
Or, maybe I misunderstood your point?

practice, if water is used, the difference in level is very very little, and also very very little potential differenc with respect to gravity, so the magnet will in any way prevent the water from dripping back to where the water started.

I agree with you on that issue.  Negligible height difference is only the problem. So, when liquid moves through thin connecting tube, it may get repelled by magnetic field existing at the end preventing the liquid from falling down.

That is the reason why I said request the NASA scientists to do that experiment.  They can create a very strong magnetic field leading to a height difference of atleast half a meter so that the liquid falling down gains some kinetic energy easily passes through the magnetic field and rests on the lower level. (liquid cannot float in mid air even in the presence of magnetic field)

The kinetic energy is reflecting the potential energy in the lifted water column. If the magnet can lift the water 0,5 meter high, there is a potential energy in that column that is released in the water that falls down. So the magnet will still be strong enough to prevent the water from going back to repeat the cycle.
The falling water will deflect an miss the input. If a cylinder is prevnting the water from deflecting away from the magnet, water will build up in the cylinder above the magnet leaving an emty space, a bubble, where the magnet is present.
