I've read in some guy's thread he glued those small magnets to the ends of that horseshoe thingy.

But try to take a strong small magnet (they are really strong) and try it again. Remember the ends should be the OPPOSITE polarity so you probably should magnetize them with the opposite side of the magnet. Or so I think....

Also, it is my theory, and I may be wrong, but you should magnetize each end with the magnet side that gets repelled, not attracted. That means you are magnetizing it with the same pole, not the opposite. Though this may not be as important, since it probably does not matter where the vane goes, left or right. Or is it?
