Building a self looping "SMOT"

[elecar]

I don't know everything, elecar, but I know a false claim when I see one presented, with no supporting evidence at all.

Think of how easy it would be for you to refute me and make me look totally stupid: all you have to do is to provide real evidence that you have what you claim. What's your excuse for not supporting your claim with evidence? Are you just being polite to the "forum know it all" ? Refute me. You cannot, so you will insult me instead.

Please read the whole thread and the answer is there, even in the very first couple of posts and has been repeated since. 
You are of no consequence to me TK, as I have said before you are a bully, a know it all, and some have their noses buried so far up your ass they can see out of you nostrils. But you do not impress or bother me in the least. You are nothing but fodder to play with and abuse. You reap what you sow TK, you don't get respect from me without showing respect. How about you read the thread and then come in with you comments  and questions ?

Hi telecom, the effect is self explanatory, as the ball reverses in the magnetic field (see video) it moves from the strongest part of the field toward the weakest.
As it reverses under gravity it is still in the magnetic field, but which way is it going ? Is it being pulled up from the influence of the magnets ? or is it traveling backwards under the force of gravity ? Which one is having the greatest influence ?
When it is in the weaker part of the field it is diverted, gently away from the magnetic field and on to the downward incline. Gravity then takes it back to the start.

Remember the drawings here are a guide, you need to keep the two sections of track from the junction as close as possible until you are in that weak field. There are no "tricks" you just have to get the magnets and junction right, it took me months to get it right.

Ok, I understand what you are saying.
in this case it is probably more realistic to draw the junction at some distance away from the magnets. In this case magnets would push the ball forward, where the gravity could take over. Than the ball will reverse and slide down into the circular branch.
Have I understood this correctly?

Someone suggested to have a spring at the end of the straight section to deflect
the ball. I think this is a very bright idea which will allow to preserve the impulse of the ball after its pushed out from the magnetic field.

Can you please provide the link to the video you are referring to?
Thank you for being patient!

Hi Telecom,  The spring idea might work, I do not know. But as I stated I did use a wedge of acrylic and even that was enough to stop the ball. So a spring may well impede the ball also I really do not know.
The video is on the 2nd page of this thread, the post above the video link explains the tests being done (for some reason I could not add the video to that post after I had posted the text.

Hi Telecom, sorry for not answering all the question.
You need to position the junction around a 1/3rd of the distance the ball rolls in reverse. I suspect 1/2 way would be even better.
You can work out the distance by seeing how far your ball travels from the start of the ramp to where it starts to reverse, then place your junction a minimum of 1/3 back. Keep the return track at as shallow angle as you can, the ball will readily roll out of the weaker part of the field but will not roll out where the field is strong.

Thank you, I more or less understand now.
It also very much depends on the shape, position and other variables of the array
of the magnets.No wonder it took months! I can see lots of tedious work, even with the info you provided!
