Need some help for my homopolar experiment!

[blueplanet]

Folks, I have been doing a homopolar experiment for some months, but so far, with very little achievement. My experiment is based on the following setup  (see the attached diagram).  I was expecting a pure DC output, which was what other experimentalists got, but I ended with a AC output in addition to the DC.  The AC output voltage is much higher than the DC. The AC output is measurable by a digital meter or a analog meter.

Right now, I am not sure if the AC came from the the drill. Apart from the drill, I do not have any other magnetic interference in my place. Could anyone tell me how to fix the problem?

Thank you in advance.

Your problem may not be a problem , but a blessing . Remember that you can feed AC into a transformer , and step up the voltage . You are not the first to get AC from a homopolar . Go toWWW.free-energy-info.co.uk This is a book by Partick j Kelly . See chapter 13 page 6 . a description of a homopolar generator by Peter Lindemann et al .

OK .now some questions of my own . According to Wickipedia , and other sources , a homopolar using a permanent magnet or magnets , works just as well if the magnets are fixed to and rotate with the disc . If this is true , then there can be no posibility of lenz law lugging , so the biggest losses are to brush friction . Peter Lindeman talks about 1000 amps ! So if we are getting only 1 volt , that is 1 Kw . Devide that by 10 to be on the safe side , and this device still has to be WAY overunity . Some sources say a copper disc , and some just a conducting disc . So best to use copper to be safe . Does anyone have a link to other sources of info on Lindemanns machine , other than Patrick Kelly`s book ?

When the magnet is stationary, then the rotating disc/circuit will cut the flux.  When the magnet/disc is both rotating together, then the stationary external circuit will cut the flux (assuming the field rotates with the magnet).  If the field doesn't rotate with the magnet, then the rotating disc/circuit will cut the flux of the stationary field.  Regardless of what part of the circuit cuts the flux (rotating or stationary circuit), lenz will still be there.  In order to avoid lenz in a HPG/HPM, we need to have a setup where there is no relative motion between the disc and external circuit.  An open external circuit may be another option to avoid lenz.

Lenz law is useless in the homopolar case. The eddy current is always there, but this eddy current is not due to the change of flux in time domain.
