Magnetic Engine Video

The point about the eddy current braking or damping is that it is a _loss mechanism_. So is the inevitable friction of the shield with the rolling ball. So you have at least two loss mechanisms operating in the shield system that you have presented. There is no corresponding input of energy to overcome these loss mechanisms, except your hand powering the motion of the shield. Remove that source of external power and your pendulum will quickly come to a stop, because you cannot remove the loss mechanisms.

Coming on your own line of thinking :

Input energy = Enregy supplied against eddy current damping + energy supplied to overcome friction between ball and shield
                    + energy supplied to overcome friction between ball and magnet.
               
                    All the energy is supplied by hand.

Output energy = Energy developed due to strong repulsion between two magnets.


What makes you think that output energy developed by strong repulsion between magnets is less than the input energy supplied by hand?

As you can see output and input are happenning by two different and independent processes. If I bring a repelling magnet near another strong fixed magnet (in the absence of shield) and release my hand,  then we can say that output energy developed by repelled magnet is equal to energy supplied by hand to bring it near the fixed magnet less losses.  Can we apply same rule to this experiment also?

Sorry for the interruption , I've never seen TKs' video could somebody provide a link please?
Thanks artv

Maybe his teacher was referring to Teslas quote


Today's scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality.[/font][/size]

Mr.Vidar,

Consult a physics professor, find out the exact energy equation and compare the input / output energy. Take your own time.

You are exactly right. Shield moves easily on the surface of magnet because it is parallel to the surface of magnet and experiences uniform flux theoughout in a parallel plane. It gets stuck at the bottom of magnet stack when it tries to move out of magnet.  I think now you have tried and realized. 

Shield will not move in horizontal plane because it is held with attracative force from the strong magnet on left side also.  That is the reason why I have said keep the fixed magnet very strong and moving magnet weak.
 
Once again I request you to build the engine as seen in my video and verify it.  Please don't make things complicated.
(I am getting bored!)

Take away friction/loss the input- and output energy is equal.
Don't get bored - this is suppose to be fun discussing and play with :-)

About eddy current: Using a shield of ferrite/ non-conductive magnetic material will solve that problem.
