Causing levitating magnet rotation

[r6900]

I have a device like this one: http://www.youtube.com/watch?v=kA_hw_lY-OY (All of them work the same)

Here's an image:

I want to make it spin without touching it with hands.

I tried using magnets of several kinds, and tried to put them in many places around it but it didn't make it spin. It just made it to vibrate a little.

I guess there is a point in which the "pen" will spin and spin. Basically, I prefer to make it rotate not with magnets, but with an electric current. Most likely, I will use an AC generator, and it also makes sense, because I thought that in some point there will be same poles, and then the pen will spin a little bit, and then there will be different poles, but the alternate current changes the poles each time, so the poles will always be the same.

My question is: in what point should it happen?

In other words, where and how should I place the magnets, or where and how should I choose to put the AC generator?The best way to make this device spin without touching it is to use an electromagnet. You can place the electromagnet near the device and it will create a magnetic field that could cause the device to spin. You can adjust the strength of the magnetic field by adjusting the current going through the electromagnet, so you can make the device spin faster or slower. You can also adjust the angle at which the electromagnet is placed in order to get the best spin effect.
