How about you let run till it drills a hole threw your battery
-
it does work but why does the screw spin?
-
instead i think i might do another one but it will be easier and it says that it will drain the battery cuz i am using a 1.5 v duracell and energizer battery
-
If *you* connect a wire almost directly from one end of the battery to the other, does the battery drain fast? 'Cuz some people would use common sense.
-
does the battery drain fast cuz you didnt explain that in your article!!!

Follow the link, read the article. Works fine since the 1820's.

@oskay does the magnet have to be a neodymium magnet? or can a ceramic disk magnet do the trick?

I'm having difficulty making the magnet/screw spin. It'll only spin half-way around and then stop. Are there any suggestions as to why this is happening and the motor isn't working?

Motor or battery is too weak, or perhaps the magnet's coating isn't metallic.

Copper isn't magnetic. If your wire sticks to the magnet, it may not actually be copper.
