SMOT! - (previously about the OC MPMM)

@tinu,

This incorrect. At B the ball has energy exactly (mgh1 + Mb) and nothing of the sorts you claim.
...

Huh?!!
This is high school physics.

@tinu,

Of course.

@tinu,

The ball free falls from B to C. Correct. Who, however, supplied the energy to bring it at B from C in the first place?

In point 2 you incorrectly state that in going from B to C it loses energy from |(mgh1 ? (Ma ? Mb))|. The correct statement is, in going from B to C it loses energy from (mgh1 + Mb) which the ball has at B. Get it?

1. The magnetic force is greater in point C than in point B. Therfor.

2. The ball finds its resting point rather in point C than point B. That means loosing energy while going towards point C.

You're getting blind as you visually are seeing that point C is in higher level than point B. Visually, in respect to level A it is, but in the magnetic loop, point C is virtually at a lower level than point B - else the ball wouldn't move from B to C. Hence the ball will drop visually upwards to this point C. However, when the ball drops beyond point C it goes virtually uphill a bit, as the magnetic field in point C is not shut down and is therfor holding back the ball for a moment, before gravity force is greater than the magnetic force and the ball is accelerating towards point A. In the drawing below you'll see how this SMOT is working if we make an pure gravitally equivalent:

@Low-Q,

If you now understand that at A the force of the magnetic field is weaker than at B, I agree.

It has by fault been claimed by me that poit A has greater magnetic force than point B - because I forgot to write "at point C". I however, never ment that A was greater than B, but that Ppoint C is greater than B.

@Low-Q,

Emphasize on this:

"2. The ball finds its resting point rather in point C than point B. That means loosing energy while going towards point C."

and tell me who provided the energy the ball has at B to be able to lose it, as you  say, while going towards C. Someone must've pulled it (spent energy to pull it) earlier from C to B to allow it now to lose that energy while, as you say, going from B to C. Who did that?

I asked @inu the same question but haven't gotten an answer from him yet.
