Behavior of a cylindrical magnet

Click For Summary
SUMMARY

The discussion centers on the behavior of cylindrical magnets when rolled on smooth metal surfaces. Participants noted that the magnet does not roll smoothly due to the non-uniform magnetic field and the orientation of magnetic domains within the magnet. This results in a preferred orientation that causes the magnet to resist movement and 'pop' forward instead of rolling continuously. The phenomenon highlights the impact of magnetic properties on physical motion.

I noticed when I stick a cylindrical magnet on a smooth metal surface (longways) and roll the magnet along the surface, it does not roll smoothly. Instead, it seems to resist movment, then 'pop' forward into another position. It is almost as if the magnet has a preference on which side sticks to the surface. Anyone have any ideas about this?

The magnetic field or (orientation/distribution of domains in the cylindrical magnet) are not uniform, and therefore there is a preferred orientation, and that would interfere with the 'smooth' motion.
