Magnet repulsion distance calculation

Click For Summary
SUMMARY

The discussion focuses on calculating the repulsion distance between two Neodymium magnets with a pull force of 10 pounds. It highlights the complexity of such calculations, indicating that while theoretical equations exist, practical testing often yields more reliable results. Participants emphasize the difficulty of accurately predicting the distance due to the non-linear nature of magnetic fields and suggest simulation tools for better understanding. Overall, the consensus is that empirical testing is preferred over theoretical calculations in this scenario.

PREREQUISITES
  • Understanding of basic physics principles related to magnetism
  • Familiarity with Neodymium magnets and their properties
  • Knowledge of magnetic field equations and forces
  • Experience with simulation software for magnetic field analysis
NEXT STEPS
  • Research the mathematical equations governing magnetic repulsion, such as the inverse square law
  • Explore simulation tools like FEMM (Finite Element Method Magnetics) for modeling magnetic interactions
  • Study experimental methods for measuring magnetic forces and distances
  • Investigate the effects of environmental factors on magnet performance, such as temperature and material interference
USEFUL FOR

Physics students, hobbyists in magnetics, engineers designing magnetic systems, and anyone interested in practical applications of magnet repulsion.

hey, so let's say i have 2 Neodymium magnets with a pull force of 10 pounds and set them at a position where they repell themselves. so my question is: how can i know in what distance will the top magnet be from the other one?
if there's and equation for that or an explanation, please tell them, they will be very welcomed.
p.s. I am not very good at physics, so if you somehow find this question as a stupid one just so you'll know.

If you know details about the magnets, you can probably simulate it. In general, those systems are hard to calculate, and testing is easier.
