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?

[oskay]

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

[truchowski]

everytime i try to do it the copper sticks to the magnet and yeh i cant do any of thoes magnet tricks idk why :(

[oskay]

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

...Just test the goddamnit batteries!

[shalenjoshi2]

How about you let run till it drills a hole threw your battery

[sandra1234310]

it does work but why does the screw spin?

[sandra1234310]

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

[oskay]

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.

[sandra1234310]

does the battery drain fast cuz you didnt explain that in your article!!!

[oskay]

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?
