Gravity Magnetic Motor

Here is my set up....I added a pendulum made of copper to swing past the sticky spot...where can I buy MUMetal??

I know its not a tri gate thread but here is something I dreamed up in 3D

The roller (as others have shown) goes in curved path and also uphill. So it should be possible to return it back using gravity assist (its own weight or with extra weights) and use the momentum (not the weight actually) to break past the entry point.

Counter weight can be used on the other side of the arm to effectively reduce the weight of the roller or you can add more weight on the same side to increase it.

How many degrees the wheel go when you just let it drop from 12 oclock, without the magnets ? (without the pendulum)
And how many degrees the wheel go when you just let it drop from 12 oclock, with the magnets ? (without the pendulum)

And is that an LED ?

Hi Omega_0,
  I have actually tried this a while back and I think this is what led me to the conclusion that a setup of tri-gates in a circular fashion as in your 3D model ( which is very good by the way , big thumbs up    ) with a roller mag entering and exiting the array on the same plane is a non-starter unless something can be done with shielding the entrance and exit..     but again, I would love to be proved wrong. I think the secret to getting a working system with tri-gates would be to get the roller mag to enter/exit the array at as near as 90 degrees as possible so you eliminate the problem of the repulsion/attraction and the ends.

I will be curious to see how the trigate work with it.

Hi AB,
   I have done some tests with a tri-gate setup as in the picture I post in this thread not 100% setup as in the picture but same principle only using 1 pair of arrays. The test i have is a wind down test now to be honest it wasn't done very accurately it was done with a watch with a second hand and a hand spin with and without the tri-gates in place. But it was very promising there was a good 10-20 secs more spinning with the arrays in place and this was consistent until the arrays were slightly out of the sweet spot. The problem with me I really like building side of things and get very impatient when I only have 1 build on the go at any one time, and at this moment I have another 3 builds on the go so I tend to flit between them as and when I can. And now the hold up on the design shown in this tread is the fact that I would like to get more of a oval movement from the pendulum instead of more of a triangular movement. So any suggestions are most welcome  ..
