I tried something similar using a amorphous alloy toroidal core as my loop, and a long piece of thread. It is when you place the magnet underneath the loop, it pulls on that loop, creating tension on the thread, further unraveling it thanks to the extra tension the magnetic field creates. At least that's what I observed (my thread, and I assume yours, is not a single filament, but many stranded(twisted) together, very small.
@ericsclips Yes, the string is multi stranded or it would not work. This could also be done by just attaching a weight to the end of the string. Basically the string has potential energy once unraveled.
@ericsclips Well...free energy is during the unravel which the magnetic force is doing for you. After the magnet is removed there is potential energy in the string and that's free naturally. This could work well on a large scale.
Without doing the math, I'll just throw out there that it will take work to remove the magnet from beneath the wire. And the amount of force it will take to remove it (from its attraction to the loop), will be equal to the amount of force the magnet exerted on the thread causing it to unravel.
As the thread unravels, it moves closer to the magnet, deeper in the magnetic field, and the flux gains a greater hold or attraction to the loop. So the longer you let it 'unwind', the more effort will be required to remove the magnet.
Nice demo but does your Mom and Dad know you put a hole in their ceiling? :O)

@valveman12 he he, holes in the ceiling is only one of the things i have been doing lately :)

Right. So there's no 'free' energy to be had here. :)

You use energy to take away the magnet
