I had someone tell me of these videos on You Tube
after I showed them the copper pipe & magnet trick. (You Tube it)

There are several designs, I used the heart and modified it w/ coils.
The "Heart Shape" Copper Wire design is easiest to get to work.
1) 1.5 AA Battery
2) Neodymium Magnet(s)
3) Piece of Copper Wire

4) A small dimple made into the (+) Top end of the battery with a center punch, some adjusting, and you have a working motor !!
