Magnetic Permeability Calculator
Find absolute permeability from relative permeability.
Permeability describes how readily a material supports a magnetic field.
The math behind it
μ = μr · μ₀, where μ₀ = 4π × 10⁻⁷ H/m is the vacuum permeability.
Worked example
μr = 200 → μ ≈ 2.51 × 10⁻⁴ H/m.
FAQ
What has high permeability?
Ferromagnetic materials like iron, often with μr in the hundreds or thousands.
