@ per oni : the resistance of my disk is 1 ohm...should hav atleast shown 0.1 o some amps but it dint show any...should i go fr Cu disk ?... I even supplied 5amp @12V between the periphery and the centre to see if it atleast rotates but it dint rotate too !
I've made a homopolar generator using Al disk, its giving me a output voltage of around 0.1V but shockingly der is no current ! a checked the resistance of the disk its very low as required, i checked for every other problem like : improper contact , smoothness of the disk , symmetry of the...
