Strength of magnets in an array

Click For Summary
SUMMARY

The discussion focuses on creating a magnetic surface using neodymium disc magnets arranged in a checkerboard pattern to maximize strength when holding ferrous materials. The proposed setup includes one-inch diameter magnets embedded in a machined aluminum plate, covered by a 1/8" plastic sheet. Key considerations include the spacing between magnets and whether they should touch at their edges to enhance magnetic field strength. The arrangement aims to ensure that adjacent magnets have opposite polarities for optimal performance.

PREREQUISITES
  • Understanding of neodymium magnet properties
  • Knowledge of magnetic field interactions
  • Familiarity with checkerboard array configurations
  • Basic machining techniques for aluminum plate preparation

Hello all,

I need to make a magnetic surface using neodymium disc magnets... the purpose for the surface is to hold on to a sheet of ferrous material, as strongly as possible.

I tend to want to assume that a checkerboard array would be best... alternating the poles of the magnets in the array, so that the closest neighbors of each magnet are in the opposite orientation.

Imagine one inch diameter magnets secured in a machined aluminum plate... a 1/8" plastic sheet covering them... the ferrous sheet would then be on the top of that.

So the strength needs to be understood in terms of the spacing as well, in case that makes a difference.

Also, should the magnets be touching at their edges, or should there be some space in order to maximize the field strength across the array?

Thank you ever so much.
