An interesting experiment in magnetism

In the video you can observe that a small disc magnet released from the edge of a ramp (non-magnetic plate) moves from the region of lower  potential to higher potential, gaining kinetic energy.  Due to kinetic energy it moves over total length of the fixed magnet but does not again make up the ramp.

Question is,  if strong neo magnets are used will the moving magnet make up the ramp again completing the loop?  (I have used ferrite disc magnets)

The "stick spot" will still be there if you use
stronger magnets. 

The force and speed of the moving magnet may increase,
but also the strength of the stick spot will increase.

Nice experiment. I like how it moves farther along the magnets counter clockwise than it does clockwise.

I agree with Floor. I would try making the magnet that moves heavier by adding something non-magnetic to it like epoxy putty.

Wish you good luck.  This experiment can be done using a ring magnet also.  I have posted a video.  Please have a look.

Is it possible to eliminate sticky point by using a combination of magnetic (steel) and non-magnetic plates?  If a small steel plate is provided at the beginning of the ramp, it may absorb the flux at that area and eliminate the sticky point.

The operation of the force vectors is similar to that of the 'smot'
What is interesting with these types of magnetic systems is:


The force differential changes with the rotation of the smaller magnet.
This is of course a function of their relative diameters, but often one will find
that over the course of repeated experiments, the "sticky spot" may move!
As the smaller magnet does not often commit to an equal number of turns
per revolution, it is facing a slightly different direction each time it encounters
a magnetic boundary.


Should one accidentally find a perfectly proportioned pair of circles
You will experience the baseline effects that John Searl exploited in his devices.
