Super simple way to see proof Pseudo Solid principle works using ring magnets

[norman6538]

Floor here is my modified experiment.

2 identical matchbox car floors (no bodies) should have the same friction 
on a ramp. The car closest to camera with extra magnets and one
under the floor and thus closer to the metal and also with
extra weight stays in place while the other
car with less magnets and less weight rolls down the ramp.  why?
I expected the heavier car floor to go down the ramp but instead
the lighter car went down the ramp. So I assume the factor was
the magnetic force that held the heavier car in place.
Double checking  I swapped car floors to make sure there was no performance difference
in one car over the other and the results were the same.

Webby1, good point. I'll work up something else to check the friction issue.
Butch has claimed several times that friction is the problem.

Great ! better test methodology.  Buy you are still changing more than 1 variable at a time.
1. weight of vehicle
2. strength of magnet
3. friction on axles

      It's impossible to do analysis of the results with out precise details of the weight change / friction change
      / magnet strength change or...............

     A simplification of the experiment, that is to say reduce the number of things that change during the
     experiment to one change at a time.

suggestions

1. Use a different rolling device.  The friction at the wheels and bearings MUST increase with increased force pressing upon them.
        In your experiment, both the stronger magnet and the greater weight increase this friction. The use of  stronger wheel and
        axle sets will not prevent the friction from changing during the varying conditions, however the amount of change in force you
        cause by swapping magnets (while using most styles of axle sets) would be insignificant under the conditions of your
        measurements. (not so with hot wheels)
2. Add weight to the lighter weaker magnet (on the top) until it is the same weight as the stronger heavier magnet. Use a non magnetic
    material,  maybe lead sinkers taped onto it. This will eliminate one unneeded variable when you swap magnets. Under the
    conditions of the experiment a SMALL difference in the weights of the magnets is probably not very significant. The differing
    magnets  strengths, is I suspect the major variation.


    One additional experiment you might try.
 
      Using a thick (new) roll of aluminum foil.

      1. Check to see if one of your strong neo magnets is attracted to it.
      2. While holding the roll of foil in hand, with it's long axis vertical, drop the same magnet
      through the center of the cardboard tube / aluminum foil roll.
