Overunity Device using Magnets in the 1920's ?

... dunno how this post happened ...

Did it not go past the strongest point of attraction at all? Wasn't the strongest point at center? I thought it would go just passed center then back unless the polarity was switched when it just passed center, which is a must if you want it to rotate.

Are you trying to switch the polarity during the first attraction? If so, there is no way that can work. It must be switched at the precise moment it passes the center. Not at center or before.

I understand that may be hard and or impossible to do with your design because of the switching polarity not being stationary. It would have a much better chance of passing the center if it was stationary.

There are a few things that I am unclear about with your design. One of them is the timing you have as well as the time length of your pulses.

Another was the rotation speed. The faster it goes, the more of a G force affect it will have. Even at a slow rotation, you are still going to have a G force factor you will have to compensate for. Was that figured in to it? Based solely on that alone, I would be very hesitant on even trying that design. There are just to many factors involved that would require using more energy to get passed them.

I am assuming the sound signal worked for creating and switching polarity's, am I right? If they did work, why not use it in design like I posted earlier or even yours but with keeping the cores stationary?

Before you throw the baby out with the laundry you may wish to consider these...

1. The swinging metal portion should be only slightly ferromagnetic. A high grade of stainless steel or bettter yet, aluminum, should act more like you wish. The aluminum will only react to magnetic fields when it is moving in relationship to a magnetic field or within a mag field that is changing.

2. The metal swing needs to be moving within the excitation coil otherwise it can only represent the coil, not the coil and the equal (and not quite opposite) reaction of becoming ferromagnetic while moving within those two fields.

Remember:
Aluminum is Paramagnetic NOT diamagnetic like copper. As such it has the ability to be temporarily ferromagnetic.
The point between poles of a horseshoe magnet has been proven to provide torsion/spin in association with specialized micro-structures - maybe swinging isn't the only thing goin on and that is the straw that will break the OU back.

Cheers!

I think we knew the answer to why this motor cannot work, the armature when over the "pole" of a PM becomes polarized in an opposite sense and is thus attracted. We know this because it happens in each and every PM motor we know of. I think Wesley Gary had the answer, the armature cannot leave the magnetic field thus cannot interact with the magnetic poles only the field "between" them. Or the armature can leave the PM field and interact with the field between them but cannot interact with the poles in any way. We should ask ourselves why we keep doing the same things over and over with the expectation of getting different results when there can be none. Here is a question, what would happen if the armature could not be polarized by the PM field in any way? ,if the armature could polarize "itself" but not be polarized by external forces
(the PM poles), in this case there is action without reaction because a reaction can only occur in the PM field and not the armature, the source of the action.

Now that we have all the magnet experts here, I have been thinking that we need a material that behaves as a ferrous material when say a DC current is passed through it or
some kind of additive to iron to make it behave non-ferrous on demand. No one would have thought of non magnetic stainless steel so this idea is not so crazy.
I wish I had paid more attention in my metallurgy classes.
