Your thoughts on this magnetic device ?

I think that the perpetuator some how influences the spin, causing it to not degrade.

Hi Bill,

Yes, what you've said makes sense. I'm still trying to understand the mechanics of it better.

Here's an interesting link which explains some of the Physics behind it :

http://www.its.caltech.edu/~atomic/d...isplaycase.htm

Some of the things I'm gathering from this info are :

- The top is a magnet and as it interacts with the magnet in the base of the Levitron, this induced a current to flow
- The base keeps providing energy back up to the top
- The base makes the top stable, which prevents it from falling

Maybe someone with a better physics background than me can help 'crack this case'.

Check out the info at the end of the link I've given. It gives an interesting history of the display case which one of these Levitron devices was kept in. See what happpened to the device on Jan 31, 2000 !!
