Does the Inverse cube law apply for magnetic repulsion?

In summary, the conversation discusses whether magnetic attraction and repulsion follow the same laws and if one is stronger than the other. It is stated that both follow the same law, but the strength of the forces depends on the distance between the magnets. While attraction can move the magnets closer together, repulsion is weaker at a fixed distance.

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.

Related to Does the Inverse cube law apply for magnetic repulsion?

1. What is the Inverse Cube Law?

The Inverse Cube Law is a principle in physics that states that the force between two objects is inversely proportional to the cube of the distance between them. This means that as the distance between two objects increases, the force between them decreases exponentially.

2. How does the Inverse Cube Law apply to magnetic repulsion?

The Inverse Cube Law applies to magnetic repulsion because the force of repulsion between two magnets is dependent on their distance from each other. As the distance between two magnets increases, the force of repulsion decreases in accordance with the Inverse Cube Law.

3. Is the Inverse Cube Law always applicable to magnetic repulsion?

Yes, the Inverse Cube Law is a fundamental principle of physics and applies to all types of forces, including magnetic repulsion. However, in certain situations where other factors may come into play, the law may not be strictly followed.

4. Can the Inverse Cube Law be used to calculate the force of magnetic repulsion?

Yes, the Inverse Cube Law can be used to calculate the force of magnetic repulsion between two magnets. By measuring the distance between the two magnets and plugging it into the formula, the force of repulsion can be determined.

5. Are there any exceptions to the Inverse Cube Law for magnetic repulsion?

In general, there are no exceptions to the Inverse Cube Law for magnetic repulsion. However, in certain situations where the magnets are not perfectly aligned or other external forces are present, the law may not accurately predict the force of repulsion.
