The goal for my experiment was to keep the parts in motion as long as possible. This was accomplished by minimising the friction - the needles have a tiny contact surface.
This "breakdance needle" makes me happy as a child!
The big cube magnet (see below) is hanging from a metal lamp shade. Other metal objects of a certain height will work just as fine.

The big cube magnet (see below) is hanging from a metal lamp shade. Other metal objects of a certain height will work just as fine.
A W-05-N and a K-08-C is attached to the needle below.
Place this "spinning top" or "breakdancer" on a smooth surface underneath the metal object. In my case it is a glass table top, but you can also use a flat plate.
The "spinning top" rotates really fast and almost frictionless on the smooth surface. The sphere is at the very bottom.
Here you can see the construction of the Y part in detail. I used 8 W-05-N and 11 K-08-C.
The cube at the end is then connected to a needle.
Note from the supermagnete team: The cube on this picture is not one of ours. For this application it looks a little over the top - a W-12-N cube magnet from our shop would do the trick just as well. If you want a larger magnet for a visual effect, you can also use THE GIANT.
