Hello all,
Its been a while since I have been on the site after proving to myself that a purely simple mechanical gravity wheel will not work. Now however I came up with a new thought on the old idea. At least new for me. Without wasting yours' and my time I just wanted to ask a few simple question about how magnets interact just to check my thought processes before I try the experiments myself.
If you take a look at my simple diagram below you see a fixed magnet (B) on top, and a free magnet (A) tethered to the fixed surface below it. The magnets A and B are within proximity of each other so that A will just be close enough to start pulling up to B. (See the little horizontal line to the left of A).
Now if we look at part 2 of this graphic you see A was pulled up to B as close as the tether would let it go. Now we attach a line from a weight (C) to the right side of A.
Part 3 : This pulls A horizontally away from B thus pulling it to a point were it looses magnetic attraction to B and falls free.
So where am I going with this?
Q: My question is how much does C have to weight for it to be able to pull A away from B?
Q: Does C have to weigh greater then A, equal to A, or could it be less then A's weight?
Q: Do you have to pull A the same distance horizontally away from B compared to the distance A moved up towards B?

Basically another way to put the question is does it take the same amount of work to pull two magnets apart as they would have generated when they attracted together? From what I know the attraction and repulsion forces are equal. Correct?
And if they attract together from the same orientation/angle that they are pulled apart from then the amount of work should be the same (Force X Distance). Correct?
Also would it be true that it doesn?t matter the angle you pull the two magnets apart from compared to the angle they were attracted together from? For example they are pulled straight together but instead of pulling them straight apart you slide it off. Which, is easier but should take the same amount of work? Correct?

Wrong!

Force example of Neodymium Magnet N42 at 25mm dia x 10mm:
Pull force generated by two magnets attracting each other is 54 kgs
Repulsion force generated by two magnets in repel is 33 kgs
