Can you measure the current?
If the battery is getting warm and losing power then I would say the coil resistance is too low, how many turns of wire? can you measure the DC resistance of the coil?

ive    tryed  a 9volt battery  on this wiring configuration and  it  seems that   at  the start the magnet spins fast ,then at about 4 min in  the  battery starts to get  warm
then its stops      at  the  start the battery read 8.70volts  and  when  it stoped it  read 8.60       ...its  has  power but  it  wont  spin it.       but  when i  leave the battery to cool in  starts back up again      any  ideas?

the  tube im  using is 4"dia   but  im  not  sure how many  turns, maybe ..150..200 with 20ga wire....i  measure the resistance  its is 004.8 ohms       here's a video of my problem http://www.youtube.com/watch?v=ZoQdZUILe8s

Hi,
you need much more wire in your setup.
The DCresistance should be around 200 to 300 Ohms
in your configuration,so try to get more wire and add it
onto your coil. Just use the same 20 gauge wire, but add a few
thousand windings until you get around 200 to 300 Ohms
DC resistance.
Then your battery also will not die.
Also try to place the tape on your axis onto a different angle,
so the spark will be bigger.
It depends on when you switch on ( fire) where the position of the magnet is
inside the coil.
Go for lower RPM and more sparking.
This will generate more back current pulses during the sparking and keep
your battery fresh.

Also you can then try to put an 1 to 3  Watt incandescent lamp in
series with your coil.

Woah!
If you intend running off a PP3 9 volt battery, then your coil resistance must be much higher!

9 volts / 004.8 ohms = 1.875 amps, thats wayyy over a PP3 batteries limit
I've got approx 720 turns of single core telephone wire on mine giving approx 23.3 ohms, I would not attempt to even put a PP3 on that!
As has already been pointed out, you need in my opinion at least 2000 turns, I think 20 gauge is a little thick, but you don't want it much thinner either as this will cause DC resistance to rise and most of the energy will be lost to heat dissipation.

i some how stumbled along your thred and i think it is awsome ok butt


i have given the newman motor generator much thought and this  is what i think and for give me if it has been already covered some where he uses copper pipes in his big generator right so there are round magnets inside of it and the weight of the magnet helps to offset any restance torque it uses gravity aswell i thought that the magnets free ride inside the copper pipes and work similar to a gravity motor but agin this in my opinion

i have not built it but i spent some time in the past working out how it all worked or how it made sence to me

keep up the good work
