mechanical maglev magnetic levitation aluminium tubes university project

maglev project with 38mm dia. 6mm wall thickness aluminium tubes, surface speed of tubes can range 0-52mph, speed in video around 22mph, magnets used: 5 x 3/4" dia. 1/4" thickness n38 neodynium magnets.
anyone know how to calculate the repulsion force induced?

So if a train traveled along an aluminium track fast enough with permanent magnets under it that were powerful enough it would levitate!

@Madkite yep, its the principle behind Inductrack maglev trains

[wbeaty]

Reversible motor, try both directions!

[howdoyoueatyours123]

@wbeaty i have! seems to work better the way shown in video, although very unstable as likes to be flung away from between the tubes, hence the popsicle stick cradle!

You could try moving the pipes apart a bit; I think they're too close together; electrodynamic levitation can be stable, but I think Earnshaw is getting you anyway at the moment!

Use small diameter magnets. I suspect with smaller magnets there will be increased stability. It looks like the magnetic field is bleeding over the edge of the rotors and introducing too much repulsion.
