Experiment with Rotating Magnetic Field
« on: October 07, 2012, 09:50:23 AM »
 
Creating a rotating magnetic field using a diametric magnet

Sorry for the quality of the experiment.   I have used junk materials.

Hi Vineet.K,

That is an interesting experiment. A idea to test is remove the short and solder two small led lights(one reversed) across the commutators and tape it to the side or top of rotor. Spin it up and see if it lights.

Thanks for sharing.

@Dreamthinkbuild
 
 
 
I don't think the power generated in the coil is  enough to light an LED.    As you can see  the size of the rotor is very less compared to the size of the magnet hence it receives a small part of the magnetic field of the diametric magnet.   Rotor is always exposed to just one pole of the magnet.  Since both are rotating,  the time of exposure of the coil to magnetic field will be more hence E=d(phi)/dt  will be less.
 
So to get a considerable power output one has to use a bigger rotor, a very strong magnet and rotate the magnet with very high speed.
 
With the type of junk materials I am having,  it is not possible for me to do that.
 
Anybody having proper components / setup can try it and make use of it,   if it is useful!
 
 
Thanks

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.
 
Regards,
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.
 
 
Regards,
 
Vineet.K.
