I'm not sure how much pressure you were putting on the shaft with your finger but it slowed down a lot also, indicating that the motor has low torque. In theory, the rotor is not supposed to loose energy as it passes the magnets if there are no eddy currents. The natural cogging effect is always pull-push or push-pull for a net change of zero, implying that the rotor should not really slow down. I still suspect eddy currents, or I am missing something.

what I used this for was to simulate the natural cogging effect felt by spinning a permanent magnet generator around, i was just load testing my motor to see if it could beet the cogging,,,

You wold have to hold the unpackaged magnets in your hand with Styrofoam insulation from a coffee cup between your fingers and the magnets. That is so that if the magnets are going to heat up, your fingers will not be touching them and affecting the readings.
I am assuming that eddy currents are being induced in the hand-held and rotor magnets causing them to heat up over time. That's the only explanation I can come up with for the motor to be slowing down.

For me the most interesting thing is that you put a load on the motor and slowed it down at the end of the clip by bring the package of magnets close to the second free-spinning rotor.
I was quite surprised by this. May I suggest that you do a new test. At the start of the test, feel the temperature of the magnets of the second rotor. Also check the temperature of the unpackaged magnets. Then apply a 50% load for two minutes and check the temps again.

Cool thanks for the update. I'm also going to make it more than one stroke,only a 1 stroke. I'm also going to have 3 sets of batteries 2 charging 1 drive that auto rotate between them selves as needed. Everyone im not in this for patents,money,fame, because I know the grater population will never see this technology at there local wallyworld period. So sharing is the key to awakening this knowledge. So i plan to share what i learn along the way. :)

P.S.S. On top of that, one may observe a 2x improvement in power output and 2x reduction in power consumption (from the same power source) by changing the magnet and coil as provided by the first suggestion. :)

I am in the same boat you're in. Welcome aboard!
P.S. The first option I suggested is way superior to the second option. When I accounted for the coil, I realized that having two of regular coils (like the one in your video) in series instead of one wide coil (twice the diameter, same height), would be each be 1/3rds as strong. My first suggestion is 50%-125% improved considering the effect of having a bigger coil. So if you take my suggestion, ignore the second one. :)
You might want to stack all of your magnets together and use a bigger coil. The torque will go up by four times: force x 2) * (distance x 2) per revolution. While the thing will only have half of the revs, the power output will still be double. An alternative method is to create another coil just like one you already use and use that to power the other magnets. This will, you will keep the rpms but you will now have twice the torque. Awesome work, great use of materials, keep it up!

Thanks for the tips, and kind review :) I have allot of plans for this motor, but at this point im saving money to get more wire,and lab equipment. I need an oscilloscope and varible power supply bad. besides wire, thats what im getting next soon as i can get the money together. This stuff can get expensive when you dont have investors, but i like it that way,theres no one to report to. I think we have the largest R&D team out there if we all stick together and share research.
