Its a neodymium magnet.

where do you buy those kind of magnet?

Tried this twice, and each time the battery was the rotating part, NOT the wire....where did I go wrong??

In the above test, you would find rotation at different speeds when the live wire hangs on the front side and on the rear side of the battery.

To make rotating light, what kind of light bulb should be connected in series with the battery? Want to know where to buy it?

To make rotating LED, what output voltage should the battery produces?

I appreciate young people like you who put the scientific principles to test hands-on, but I do not recommend you to experiment short circuiting the battery in such anti-science and anti-scientific education way

I recommend exploring how attraction and repulsion work between the horizontal wire segment and the magnet when only one side of the hanging wires is conducting instead of trying to box the wire in fear of it being thrown away.

I Tied fishing wire to it and had it hookd up to something and it reeled it in like a Boss!!!! Try it its fun!!!
