# Calculating Force Created by Opposing Magnets

• Gdarnall
In summary, the conversation discusses the possibility of calculating the amount of force created by two opposing magnetic fields with a certain amount of electrical current. The speakers mention the potential factors that may affect the force, such as the size of the magnet, the amount of current supplied, the angle of the opposing magnet, and the distance between the two magnets. They suggest using the Biot-Savart law and the formula dF = I dL x B to determine the force.

Amount of force 1 magnet with"x"electric energy can create against an opposing magnet

is there a formula which can allow me to calculate the amount of force which can be created by two opposing magnetic fields with a certain amount of electrical current?

does the size of the magnet have much to do with the maximum amount of force the field can create ?

maybe some formula involving : SIZE of magnet, amount of current supplied, ANGLE (degrees) of opposing magnet with the same energy and DISTANCE between these two magnets?

Use the Biot-Savart law to calculate the field from your wire geometry and then use dF = I dL x B to determine the force.

I can confirm that there are indeed formulas that can be used to calculate the amount of force created by two opposing magnetic fields. The force created is dependent on several factors, including the strength of the magnetic fields, the distance between the two magnets, and the angle at which they are positioned. The size of the magnets can also play a role in the maximum force that can be created, as larger magnets generally have stronger magnetic fields. It is important to note that the formula for calculating this force may vary depending on the specific properties and materials of the magnets in question.

## 1. How do I calculate the force created by opposing magnets?

To calculate the force created by opposing magnets, you will need to know the strength of each magnet, the distance between them, and the angle of the magnets in relation to each other. You can use the formula F = (m1 * m2) / d^2 * cos(theta) to calculate the force, where m1 and m2 are the strengths of the magnets, d is the distance between them, and theta is the angle between them.

## 2. What unit of measurement is used for the strength of magnets?

The strength of magnets is typically measured in Gauss (G) or Tesla (T). Gauss is more commonly used for smaller magnets, while Tesla is used for larger, more powerful magnets.

## 3. Can the force between opposing magnets be repulsive?

Yes, the force between opposing magnets can be either attractive or repulsive, depending on the orientation of the magnets. If the north pole of one magnet is facing the south pole of the other, the force will be attractive. If both magnets have the same pole facing each other (either north-north or south-south), the force will be repulsive.

## 4. How does the distance between magnets affect the force they create?

The force between two magnets is inversely proportional to the square of the distance between them. This means that as the distance between the magnets increases, the force between them decreases. So, the closer the magnets are, the stronger the force will be.

## 5. What is the strongest possible force between two magnets?

The strongest possible force between two magnets will depend on the strength of the magnets and the distance between them. Generally, the closer the magnets are and the stronger their individual strengths, the stronger the force will be. However, there is no limit to the force that can be created by opposing magnets, as it will continue to increase as the magnets get closer and closer to each other.
