I'm sorry, but I don't have any design drawings for the generator. I just rebuilt it from the original drawings. Dimensions are not very critical. If you use NdFeB magnets instead of horseshoe magnets, the generated voltage is higher. The voltage depends on the magnet's flux density, the radius of the disk, and the angular velocity. U = ω x B x (R^2)/2, where: U: Voltage ω: Angular velocity B: Flux density R: Radius of the disk
god bless! I've got a doubt regarding this subject. What if I use an ac source and also an electromagnet instead of just a magnet. If I wire the circuit of the disc and the electromagnet in series, would the generator spin? Theoretically they're both changing the current with the same rhythm
The homopolar generator (Faraday generator) in contrast to other types of generators, never changes the output polarity. The charge separation results from the Lorentz force on the free charges in the disk. Your setup suggestion will not work because it's based on wrong assumptions.

do you have the plans for this? I'm trying build one for a school project.

i saw it on reddit. impressive work, well done
Thank you very much 🙂
what is the think you used at the end to measure something, why do you need the think that black wired connected to
It's a multimeter and I measured the voltage generated (which is quite low).
@@Marbslab thank you and you also can try to attach the light bulb so you can make light
@@Lirk1s I'm afraid the voltage is too low for that. You would have to increase the speed considerably and use a stronger magnet.
@@Marbslab True, you can just rebuild that if you have time
What metal is the disc made of?
The disk is made of brass, it has a diameter of 200 mm and a thickness of 2 mm.
@@Marbslab Would copper work instead if I want to replicate this?
@@alt1812 Sure, it will work.
do you have a link to those brass feet you used? those are cool

Honopolar use, that bipolar.
