    If that's only 12v or so from your drill willi, I really have to wonder what would happen to that magnet if that coil was subjected to 70v from someone electro's coil gun :twisted:

    1000uF charged to 60V makes it fly about 1,5m before hiting the ground wen fired at 45°

    I didnt try conecting it to my coilgun (It has 3 parallel pairs of two 10 000 uF 63V caps in serial)
    and its not even asembeld right now becose i tock it a part to make an litle 3000V generator.
    But it shod go quite a distance since i get an projetile go 7m wen fired at 45°(Its siting on the floor and not the table)

    I once tryed to put that magnet in a playtic box and an coil under it.The coil was then feed 50Hz AC from an mains transformer.The magnet went wild.It stared jumping all over the box and moving the box around.Kinda fun to watch.

    Pep boys now sells a 1F ultra cap ( the kind for car audio)..with a 0.0015 ohms ESR..
    if it was cheaper i would have got one..but at $99 american i just couldnt see it..
    at .5CV^2 thats 72 Jouls energy.at 12V hmmm
    my 110F cap holds 343Jouls...but the ESR is 0.003 ohms

    edit: i found a good source for magnets , these arrived today..
    http://www.magnet4sale.com/xcart4/product.php?productid=16267&cat=256&page=4
    they are AMAZINGLY STRONG , at least twice as strong as the 1/2 "
    ones i have..and for 1.50 each you cant go wrong..
