Magnetic Force Between Current-Carrying Wires Calculator

1. About

The magnetic force between current-carrying wires is a fundamental concept in electromagnetism. When currents flow through conductors, they generate a magnetic field that exerts a force on other nearby conductors carrying current. This interaction is crucial in various applications such as electric motors, transformers, and levitation systems. Understanding and calculating the magnetic force allows engineers and physicists to design and optimize electrical devices effectively. Our Magnetic Force Between Current-Carrying Wires Calculator simplifies this process, providing accurate results for various configurations.

2. How to Use

Using our calculator is straightforward and user-friendly. Here’s a step-by-step guide:

1. Input the Current: Enter the current values (I1 and I2) in amperes (A) for each wire.
2. Input the Distance: Specify the distance (d) between the two wires in meters (m).
3. Select Direction: Indicate whether the currents are flowing in the same direction or opposite directions. This will affect the nature of the magnetic force.
4. Calculate: Click on the “Calculate” button to get the magnetic force result (F) in newtons (N).

3. Formula

The magnetic force (F) between two parallel current-carrying wires can be calculated using the formula:

F = (μ₀ / 2π) * (I1 * I2) / d

Where:

• F: Magnetic force in newtons (N)
• μ₀: Permeability of free space (4π × 10^-7 T·m/A)
• I1: Current in wire 1 in amperes (A)
• I2: Current in wire 2 in amperes (A)
• d: Distance between the wires in meters (m)

4. Example Calculation

Let’s walk through an example. Consider two parallel wires carrying currents of 5 A and 3 A, respectively, spaced 0.1 m apart. How would we calculate the magnetic force between them?

Using the formula:

F = (μ₀ / 2π) * (I1 * I2) / d

Substitute the known values:

F = (4π × 10^-7 T·m/A / 2π) * (5 A * 3 A) / 0.1 m

F = (2 × 10^-7 T·m/A) * (15 A²) / 0.1 m

F ≈ 3 × 10^-6 N

The magnetic force between the two wires would be approximately 3 micro-newtons.
