Does the Inverse cube law apply for magnetic repulsion?

AI Thread Summary
Magnetic attraction and repulsion both follow the same mathematical laws, with their absolute values being identical. However, magnetic repulsion is generally perceived as weaker than attraction, with a noted 10% difference in force. The force of both attraction and repulsion increases as the distance decreases, but attraction effectively brings magnets closer, enhancing its perceived strength. It's important to distinguish between inverse cube and exponential relationships when discussing these forces. Overall, while repulsion is weaker, it operates under the same fundamental principles as attraction.

Was just wondering is it only possible for magnetic attraction? because the force increases exponentially with decreased distance, or can it be used for repulsion. It's blatantly obvious that magnetic repulsion is a lot weaker than attraction, by a 10% margin. hence why repulsion is weaker, but mathematically speaking, do they follow the same laws.

It is not, at least if you compare the same magnets in the same magnetic fields. You rarely have that as magnetic fields influence the strength of magnets in those fields.

Both follow the same law, even their absolute values are identical.

Inverse cube isn't the same as exponential. You should be more careful when throwing that term around.

Attraction isn't any stronger than repulsion at a fixed distance, but the attraction moves the magnets closer together, and the forces are stronger at closer distances.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
