Tallest Open Loop SMOT?

[Paul-R]

if I understand the problem, its to pass the gate and still maintain or increase the kinetic energy?

People report an  acceleration on passing through the gate

Yes, People do report acceleration through a magnetic gate, but those
same people will report a "sticky spot" in a track of gates designed
into a loop. That is the runner exists the local magnetic field of the gate
but then it's residual momentum is insufficient to have it break free
of the rest of the magnets in the whole loop. That is a magnetic field will
have an radius^2 force vector in the direction of the magnets field.
That affect will be integrated over time. So people try to have gravity
assisted acceleration. If all of the initial energy of the runner is dissipated
then you are no longer in control of the runner, the magnetic field
of the track is in control of it.

The runners total momentum is it's residual forward momentum plus it's residual
rotational momentum coupled through it's running radius. I have speculated
that using a system that could switch momentum function(automatic transmission)
that might be able to preserve some momentum by switching it's coupling function
of rotational momentum to forward momentum that a fixed runner couldn't do.

A motor rotor is nothing but a caged runner running on a fixed track. Multiplying the
total energy by multiplying the runners attached to the rotor does not change the
energy balance around the loop for each.

Hello. Why don't warm up the till curie point? I did some drawing using this concept to let a gadolinium or terbium piston in a cilinder to warm the air inside the cilinder...when the piston is at the closest point we move half piston farer from the base of cilinder and the amagnetic part closer,so pression of gas don't decrease. So we can exit from attraction easly and repositionate the two halfes of the piston... this should be a magnetic assisted engine

@  ElizabethGreen
"Is there a limitation on the maximum ball mass or height of an open loop smot?  E.g. Is it theoretically possible to pull a 10 or 100 gram round steel ball to the top of a 50 cm tower? 1 meter? 10 meter."


I did some experiments a while back, using a specific configuration of magnets,  inclined ramp, spherical and cylindrical rolling objects.
That experiment / topic was called "thin magnetic ramp experiment"

It appears to me that there is not a limit to the height that can be attained. This is just a matter of scaling up in size.

But I think that there are strict limits between  the degrees of incline of the "track" and  the (mass and weight) of the rolling object, ...
if / when one desires the rolling object to escape from the track/magnets do to the "rolllers"  momentum.
