Those hablach arrays are awesome! I want one!
Thought of a good use for it too! So you have a metal rod, which is tapered so its more of like a long long cone. The hablach array is at the bottom, in a ring configuration. around this big metal cone thing is a big coil, so you have a conical electromagnet. Energize it opposite to the field the inner part of the ring has, and it'll go shooting off one direction, until it bumps into the opposite pole. Makes for a good brake so it won't go flying off, and the upward pulling motion could be useful for something, maybe to operate a piston for a vacuum pump? Reverse the current and it'll work in reverse! You COULD use a standard NIB ring magnet, but it looks like the hablach arrays have a much stronger field, therefore the entertainment factor is increased.
