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.

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
