SUMMARY

The discussion centers on the magnetic properties of flat refrigerator magnets, specifically the location of their north and south poles. Participants conclude that the poles are arranged in an alternating pattern across the surface, similar to a checkerboard, with all poles on the same side. This configuration allows only one side of the magnet to be "sticky." A reference link to further information is provided, enhancing understanding of these magnetic properties.

PREREQUISITES
  • Understanding of basic magnetism concepts
  • Familiarity with bar magnets and their properties
  • Knowledge of magnetic domains and their arrangement
  • Experience with practical applications of magnets, such as fridge magnets
NEXT STEPS
  • Research the arrangement of magnetic domains in flat magnets
  • Explore the physics behind alternating magnetic poles
  • Investigate practical applications of refrigerator magnets in engineering
  • Learn about the design and manufacturing process of fridge magnets
USEFUL FOR

Individuals interested in magnetism, including physics students, hobbyists in DIY projects, and engineers exploring magnetic applications in design and manufacturing.

I have a flat rectangular refrigerator magnet. I was curious to where the N S poles were, so I took a standard bar magnet to it to find them. Curiously, the bar magnet does not seem to be repelled at any place of the refrig magnet. Where would the poles be on a flat, bendable refrig magnet?

This is no expert response; I don't actually know the answer. Having worked with the stupid things, however, I have a suspicion.
I used to make fridge magnets, screen-printing a design and then cutting out the shape. When stacking them for packaging, they like to slide around on each other just a bit and then settle down. That leads me to think that north and south domains alternate across the surface, quite close together, as if you had hundreds of bar magnets standing on end in a checkerboard pattern.

You have the right idea, almost. The poles are all on the same side, like alternating horseshoe magnets--very clever, making only one side "sticky". Check this out: http://mrsec.wisc.edu/Edetc/background/fridgemag/index.html"

Wow... that's even weirder than I thought. I kinda like that 'worm gear' thing that the guy made, but I can't imagine it transferring much more torque than is needed to just turn the 'pinion'.
 
Neat, wonder if I can find enough such fridge magnets to try that gear thing..

It's in Doc's link. Just scroll down a bit.
