This may be a little older but important basics video...   I wish that all our posts could be as educational as this video.  Very well done.

Is this the same as coil shorting?

>>added<<

Now if we could do some cool science and look at gen coils with Litz wire,  Litz wire bifilar, different coil and core types, etc. with similar setup as done in the video then get all the data together, I think we would have something to really build on. 

So many variables.... LOL   But that is my plan as soon as I get all my parts that I have on order.   Just too many of my orders (lowest ebay prices) are coming from China... LOL

Happy 4th of July for those in US.

Hello, everyone:
    Found a low-level questions, please do not laugh at me.

    On the drive coil:
    I just installed a bottom-driven coil,
    Input voltage: 12V, input current 0.65A, 1600 rpm

    When I install the top drive coil after
    Input voltage: 12V, input current dropped to 0.30A, speed down to 900rpm.

    Top coil and bottom coil connected in series,

    Questions:
    Two coils connected in series with the current down I can understand,
    But: Why the rotor speed decreased a lot?
    This phenomenon is normal?

Try connecting Bottom-Tail to Top-Head.
Best Wishes,

Hi Arthurs!

Try to switch the wires of your second coil  ( this should be the problem). See if you are running in atraction or repulsing mode, and then try to put both coils in atraction or repulsing. Remember , if one of your coils is in repulsing, the second one should  be monted in revers than the first one, if not, you'll have one in atraction and one in repulsion ( and this is no good).

Now i'm experimenting the shorting coil at TDC and there is some gain there. Unfotunatelly i'm not soo good with electronics. I need a schematic but can't find something similar. Can anyone post a schematic circuit please?
Thank you!
