Tri-Force Magnets - Finally shown to be OU?

Hi Sean.
This video is great. Can you please remove the magnets from the downhill side? Start the runner from the same point as you did in the video. In other words: only use magnets uphill and use downhill (gravity) to pass the repelling point.
See if that works. Thanks.
Eric.

Hi Eric

All packed up this end for the weekend as away again on work all week.

Will try out your idea next weekend when back.

Cheers

Sean.

@ Eric

that set-up was done in a video a few pages back.
the roller starts from a point uphill, travels down into the repulsion, ou the other side and ends up at a point higher than it started.

For those wanting to see some FEMM sims of the Tri-Force principle, I did them... (had some free time on my hands, lol)

Here is a basic one, if you want to see more, let me know...

I will of course have to host them off OU.com because of the new 50KB attachment limits ;/

Anyway, just thought someone might be interested...

Peace guys!



In this sim below the forces on the runner are: x = 1.058 Newtons and y = -0.0074 Newtons, Which basically translates to, a horizontal only movement based on 1 Newtons for force, the vertical component is negligible. (Remember, this sim is effectively a snapshot in time, so, to see the average force on the runner throughout the whole set of gates, you'd have to do some LUA scripting and map out the force values as you continually move the runner through the lenfth of the Tri-Force gates...)

Hi tao
Can you do the setup below? I have tested it and know it works but I would love seeing what the flux is doing, I have also added another Trigate in this setup and it acts the same as having one, you can get repel in when your a distance from the Trigate but that is fixed by ajusting the high our roller is from the top of the Trigates.
I have two test left with this maybe 3 and thats adding iron to the bottom, adding enough Trigates to get a semi circle and seeing if it still attracts in and kicks out and seeing what happens with the same setup above as well as below the roller.
Take Care tao
