Working SMOT ramp from Tom Ferko ?

Nice one Tom

Started playing with the only ring magnet I got here and attached it to one of my wheels as shown below.

Excuse the shaky video attached but holding camera in one hand while trying to hold a lump of magnets in the other is not ideal LOL.

Obviously in the Video my hand is moving the bar and causing the rotation, but what is interesting it how little effort is needed compared to other magnet configurations I have tried on the wheel before.
I should of got someone to hold video camera for me so I can control the bar more and show what I mean, maybe later when the kidz are in!.

Will now try fixing the magnets at the angles you specify and see what happens.

Regards

Sean.

I have been looking at your "Ping Pong" Idea. At first I didn't think you wouldn't have a chance making it work, but after thinking about it I feel you could get it started.

It would be a balancing act

• Energy build up from the ring magnet.
  This can be controlled by the angle of the beam and the distance from the pivot point and the fixed magnet. This is an important point because the weight of the ring magnet while traveling down the beam needs to gain enough energy to travel far enough into the magnet field of the fixed magnet. Once the ring magnet has closed on the fixed magnet the magnetic field will build to slow then stop the ring magnet
• Overcoming the friction holding the ring magnet fixed to the beam.
  It takes more energy to start an object in motion than it take to keep it in motion. With the ring magnet stopped and the direction of travel going up hill, the question will be if it has first traveled far enough into the field to create a force surfactant enough to break the fiction hold the ring magnet in place.
• Can the ring magnet stored the energy need to travel up the beam and past the pivot point.

After looking at this I think it could work it will just take time.

Good luck.

Hi Guys,

Read this. I need input.

Hi Tom,

I wonder if the ring magnet in itself (apart from its attractive force to the ball which is useful)  is needed for your setup to rotate?  A well ball-bearing cylinder shaped body of similar size and mass (i.e. a similar sized non-magnet ring or cylinder) would equally be supposed to rotate in the same way like the ring magnet, don't you think?  Of course here I also suppose that your original idea starts moving,  all I want to say the (ring) magnet's role is secondary here. 
In your setup the ball always touches the surface of the ring magnet alongside the Bloch wall, this seems to help keeping up a more stabil mechanical connection between the magnet and the ball.
Well, somehow I 'feel' the ball sooner or later will get stuck between the ring magnet and its rollers after starting their rotation by an initial hand-push because the resultant force of the ball's  'mg'  product comes out from the balls geometric center point (a balanced point with respect to the ball's mass) and due to this I fail to see a force that would keep up the continuous rotation. I do not think the ring's magnetic attraction towards the ball is just this force.  I would liked to be proved wrong with this opinion of course
