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
