# Two current carrying wires perpendicular to each other

• iacyclones25
In summary, when two long wires carry current at right angles to each other without touching, there is a force between them. This force can be found by using the concept of v x B (velocity cross magnetic field) and observing the direction of the forces on each wire at the crossing point. This can help in understanding the relationship between the wires and the forces acting on them.

two long wires carry current and are at right angles to each other, but they do not touch. describe the force between them

I found the magnetic field and force direction individually when one wire's current points north and the other east. I just don't quite understand the affect they have on each other. It's a concept problem. I understand the force on each other in parallel.

You just have to do $$v \times B$$ (v cross B) to find the directions. Draw the cross, and look at the direction of the forces on each wire on both sides of the crossing wire (e.g. 4 points in a diamond with the crossing point at the center).

Does that make sense? Or help at all?

## 1. How do two current carrying wires perpendicular to each other interact?

When two wires carrying electric current are perpendicular to each other, they create a magnetic field that is perpendicular to both wires. This magnetic field causes the wires to experience a force, known as the Lorentz force, that can cause them to move or exert a force on each other.

## 2. What is the significance of the angle between two current carrying wires?

The angle between two current carrying wires determines the strength of the magnetic field and therefore the strength of the interaction between the wires. When the wires are perpendicular, the interaction is at its maximum strength.

## 3. Can the direction of the magnetic field be changed by changing the angle between the wires?

Yes, the direction of the magnetic field can be changed by changing the angle between the wires. When the wires are parallel, the magnetic field is aligned with the wires. As the angle between the wires increases, the direction of the magnetic field becomes more perpendicular to the wires.

## 4. How does the current flowing in one wire affect the other wire?

The current flowing in one wire creates a magnetic field that can exert a force on the other wire. The direction and strength of this interaction depend on the direction and magnitude of the current in both wires.

## 5. What applications does the interaction between two current carrying wires have?

The interaction between two current carrying wires has various applications, such as in electric motors, generators, and transformers. It is also used in devices like speakers, where the interaction between the wires creates sound waves. Additionally, it is used in scientific experiments to study the behavior of electric currents and magnetic fields.
