@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 @tinu the same question but haven't gotten an answer from him yet.

OK, @Low-Q, don't worry about that now. Everyone makes mistakes. Focus on the question I asked you.

You have my answer posted! What part was not clear? I said ?the user provides mgh1+Mb-Ma to place the ball in B?. Read carefully if you are in mood of debating the issue.

Actually, thanks to the excellent drawing provided by Vidar I hope everyone can conclude this discussion. It is clear that the ball moves downward on the potential field and when it reaches its lowest point (A), the clever or the less clever user raise it back top hill  (in B). I?d like to remain among the clever users and see that ALL the required energy is provided by me. No CoE violation. Not the slightest doubt about it. Input energy (A to B) -> Uphill movement. Free fall -> From B back to A, through C, which is just an intermediate point. Energy is conserved.

@tinu,

This is incorrect, I already told you that. When the user moves the ball from A to B he or she causes the ball to lose magnetic potential energy. User isn't imparting magnetic potential energy from A to B. Therefore, here's the question again--who has supplied the magnetic potential energy Mb  the ball has at B (by pulling the ball from C to B) which the ball further spontaneously loses when it goes from B to C? That was the question and you haven't answered it yet.
