# Attraction and repulsion between two magnets

• kalesh
In summary, the conversation is discussing the possibility of calculating the force of attraction or repulsion between two magnets of different sizes and strengths, as well as their orientation and specific dimensions. The use of specific variables such as length, radius, relative permeability, and magnetic "moment" may be helpful in creating a mathematical model for this calculation. However, information about the torque of magnets is more readily available than information about their attraction and repulsion forces.

Hi,
I hope this is the correct place to ask this.
Does anyone know of a formula to calculate the force of attraction or repulsion between two magnets of diffirent sizes and strengths?
Also the magnets are not parallel to each other.
Any help highly appreciated.

It depends on the specific dimensions, locations and orientation of the magnets.
Give some specifics.

Hmmm, okay. Let's say you have two cylindrical magnets of length, L, radius, r, relative permeability k. What else do you need to know? Would you need to know how many Tesla are measured at different distances from the material? Would it help to know the magnetic "moment" of the magnets? Can you model it as though the magnets each consisted of two "monopoles," each subject to an Force = inverse square distance law?

There is info about the torque all over the place, but its hard to find anything about the attraction and repulsion of magnets.

## What causes attraction and repulsion between two magnets?

The attraction and repulsion between two magnets is caused by their magnetic fields. These fields are created by the movement of electrically charged particles within the magnets.

## Why do opposite poles of magnets attract each other?

Opposite poles of magnets attract each other because their magnetic fields are oriented in opposite directions. This causes the magnetic fields to interact and pull the magnets towards each other.

## Why do like poles of magnets repel each other?

Like poles of magnets repel each other because their magnetic fields are oriented in the same direction. This causes the magnetic fields to interact and push the magnets away from each other.

## What is the difference between attraction and repulsion in terms of magnetic poles?

The difference between attraction and repulsion in terms of magnetic poles is the orientation of their magnetic fields. Attraction occurs between opposite poles with opposite orientations, while repulsion occurs between like poles with the same orientation.

## Can the strength of attraction and repulsion between two magnets be changed?

Yes, the strength of attraction and repulsion between two magnets can be changed by altering the strength of their magnetic fields. This can be done by changing the distance between the magnets, the strength of the magnets themselves, or by introducing other materials that can affect their magnetic fields.
