Enter the permeability of the material, the cross-sectional area of the material, and the length of the path the magnetic field follows through the material into the calculator to determine the Permeance Coefficient.

## Permeance Coefficient Formula

The following formula is used to calculate the Permeance Coefficient.

PC = μ * (A / l)

Variables:

- PC is the Permeance Coefficient (H/m)
- μ is the permeability of the material (H/m)
- A is the cross-sectional area of the material (m²)
- l is the length of the path the magnetic field follows through the material (m)

To calculate the Permeance Coefficient, multiply the permeability of the material by the cross-sectional area of the material. Then, divide the result by the length of the path the magnetic field follows through the material.

## What is a Permeance Coefficient?

The Permeance Coefficient, also known as magnetic permeance, is a measure of a material’s ability to conduct a magnetic field. It is the reciprocal of magnetic reluctance and is analogous to electrical conductance. The permeance coefficient is dependent on the material’s properties and its geometry. A higher permeance coefficient indicates a greater ability to conduct a magnetic field.

## How to Calculate Permeance Coefficient?

The following steps outline how to calculate the Permeance Coefficient.

- First, determine the permeability of the material (μ) in H/m.
- Next, determine the cross-sectional area of the material (A) in m².
- Next, determine the length of the path the magnetic field follows through the material (l) in m.
- Next, gather the formula from above = PC = μ * (A / l).
- Finally, calculate the Permeance Coefficient.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

permeability of the material (μ) = 5 H/m

cross-sectional area of the material (A) = 10 m²

length of the path the magnetic field follows through the material (l) = 2 m
