SMOT! - (previously about the OC MPMM)

Here the steel ball is forced away from the SMOT - right before it enters it:

Don't bother. You can't prove the unprovable. Like I said, learn some physics first and then come back for a discussion.

You can't prove the unprovable.

You should take note of your own words regarding your own unproved  violation of C of E claims!

Low-Q makes a good point.  I have always wondered about this. I have experimented with magnets for a long time now, including the SMOT.  It takes "energy" to place the ball in a position to be influenced by the SMOT and this should not be ignored.

@Pirate88179,

Make no mistake, @Low-Q has no point, let alone his confusion about the difference between force and energy (which he denies but he actually has). To understand this analysis always think of the energy of the ball and of nothing else. That's first. Second, always think of the energy that the ball has exactly at A, at B and at C before it gets back exactly at A. If CoE were obeyed the ball would have lost the exact amount |(mgh1 - (Ma - Mb))| of energy, which the ball has acquired when moved from A to B, in spontaneously going back exactly along the same route but in the opposite sense--from B back to A. The ball in the discussed case, however, goes spontaneously along a different route whereby it loses also energy Mb it has at B in moving spontaneously towards C (which it wouldn't have lost if it were to go back spontaneously from B directly back to A thus obeying CoE). I've explained this many, many times and I don't think one needs to repeat it constantly because someone confuses enegy with force or has other gaps in understanding physics.
