Hi.

Im very intrested in building this device.
But before I make modifications, I'll try to achive the same results with parts that are very alike the parts you use.

Is the magnet a ceramic one?
Is the ball at the tip of the axis with the magnet needed to get a wobble effect?

Thanks.
Eric

@Eric,


Yes it is a ceramic magnet.


I have used the ball just to have a point contact with  the base.     Straight away you can use a shaft which is rounded at bottom to minimise friction and for smooth rotation of the magnet.

This is the easiest device to build but when it comes to practical use  -   you may have to conduct  a deep research into it.

Hi.

When I looked at the video again, I noticed that you keep rotating the magnet after the rotor started to rotate. I did not see that before and I asumed that the experiment showed a self-runner.

Eric.

@Eric,


It is not self running.  You have to continuously  rotate the magnet to keep the rotor rotating.   It is same of as an induction motor but instead of supplying an AC wave to a stationary core to create  rotating magnetic field,  you will be rotating diametric magnet which provides alternating north and south poles with respect to rotor.

The rotation of the rotor indicates that a current is induced in the rotor.  This current in turn produces magnetic field which is used to establish coupling with the diametric magnet. 

The magnetic field induced in the rotor will not have the slowing down force on the magnet because both  are coupled and rotating.  In a conventional generator when magnet is rotated with respect to stationary coil,  the magnetic field induced in the coil opposes the rotation of magnet trying to slow it down.

To get any practical use of the above experiment you have to tap the current produced in the rotor instead of shorting it.  This is a very tough task and requires some research work.

Vineet.K.
