SUMMARY

The discussion centers on the repulsive force between neodymium magnets of different sizes, specifically a 12 oz can and a 2-liter bottle. It concludes that if both magnets have the same magnetization, the larger magnet (2-liter bottle) will indeed exert a greater repulsive force when placed at a one-inch distance from the smaller magnet. This is due to the larger volume potentially containing more magnetic dipoles, although the actual strength depends on the density of those dipoles.

PREREQUISITES
  • Understanding of magnetic dipoles and magnetization
  • Basic knowledge of neodymium magnets and their properties
  • Familiarity with the concept of magnetic repulsion
  • Awareness of the relationship between size and magnetic force
NEXT STEPS
  • Research the properties of neodymium magnets, focusing on magnetization and dipole density
  • Explore the mathematical models for calculating magnetic forces between different sized magnets
  • Learn about the applications of neodymium magnets in various fields
  • Investigate experimental setups to measure magnetic repulsion forces
USEFUL FOR

This discussion is beneficial for students and enthusiasts in the field of magnetics, physicists studying magnetic forces, and engineers working with magnetic materials.

I am new to the field of magnetics and therefore my question will probably be elementary but here goes. If I have 2 neodymeum magnets both the size of a 12 0z can of coke and I place the cans positive pole to positive pole they will repel each other with a certain force and for argument sake say at 1 inch apart.
Question: If I were to take one of those can sized magnets and place its positive pole against the positive pole of another neodymium magnet the size of a 2 liter bottle at one inch distance apart would there be more repulsive force ?

Assuming that the larger magnet has the same magnetization as its smaller counterpart, then yes, I'm fairly certain that there will be a greater repulsive force.

BTW, remember that magnetization is the number of magnetic dipoles per volume. So a larger magnet can be weaker, if it has fewer magnetic dipoles.
