Reduction of magnetic repulsion

Click For Summary
SUMMARY

The discussion focuses on the impact of using a steel rod versus a non-ferrous material, such as aluminum, as a guide for N50 ring magnets in an assembly. It concludes that the magnetic attraction between the N50 magnets and the steel rod reduces their repulsive force, resulting in a closer resting position of the magnets. This phenomenon occurs because the steel rod influences the magnetic field interactions, which differs from the behavior observed with non-ferrous materials. The user seeks clarification on the configuration and its implications for magnetic repulsion.

Hope I'm in the right spot, google searches lead me here.

I am working with a couple N50 ring magnets which are axially magnetized, as an alternative to a coil spring. They are going around a steel rod which acts as the guide, and is an integral part of the complete assembly.

My question is, since the magnets will have some attraction to the steel, will their force of repulsion against each other be less than if I replaced the steel rod with a non-ferrous material? What lead me to ask is that I notice that the resting position of both magnets is closer when they are on the steel rod than if I substitute a piece of aluminum as a guide.

Welcome to PF. Can you provide a drawing of this? I am having trouble picturing the configuration and it is not clear what you are trying to do with this.
