Does the Inverse cube law apply for magnetic repulsion?

Click For Summary
SUMMARY

The discussion confirms that both magnetic attraction and repulsion follow the same mathematical laws, specifically the inverse cube law, although their effects can differ in practical applications. Magnetic attraction is often perceived as stronger due to the nature of how magnets interact at varying distances, leading to a 10% difference in perceived strength. The forces of attraction and repulsion are identical in absolute value when measured at the same distance, but attraction tends to dominate due to the magnets moving closer together. It is crucial to differentiate between exponential and inverse cube relationships in magnetic force calculations.

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.
