SUMMARY

To measure the force between two magnets, various devices can be utilized, including pull spring scales, load cells, and piezo crystals for precise measurements. The force is influenced by the geometry and relative positions of the magnets. A practical method involves constraining the magnets' motion within a tube and using a simple force scale to measure the push or pull. For experimental setups, weights can also be hung to determine the force required to break the magnetic grip.

PREREQUISITES
  • Understanding of magnetic force principles
  • Familiarity with measuring devices such as spring scales and load cells
  • Knowledge of piezoelectric materials and their applications

Is there any device to measure the force between two magnet?
 
Physics news on Phys.org
The force between two magnets depends upon the geometry of the magnets, and their relative positions:
http://en.wikipedia.org/wiki/Force_between_magnets

But if you can constrain their motion - put two bar magnets into a tube - you can use a simple force scale to measure the push/pull. For really close work you would use a piezo crystal, but an ordinary spring scale will work.

For example:

Pull spring scales: http://www.globalindustrial.com/g/packaging/scales/Dial/spring-scales-99102

Or a load cell: http://www.futek.com/product.aspx?t=load

Or you can just hang some weights ... and see how much it takes to break the magnetic grip. Slip something between the magnets to control the spacing.
