Magnetic Permeability Calculator

Find absolute permeability from relative permeability.

Calculated Output

Absolute permeability (H/m) 0.0003

Formula: μ = μr · μ₀

Step-by-Step Breakdown

1. Values used:

2. Relative permeability μr = 200

4. Absolute permeability = 0.0003H/m

Did this calculator solve your problem today?

The math behind it

μ = μr · μ₀, where μ₀ = 4π × 10⁻⁷ H/m is the vacuum permeability.

μr = 200 → μ ≈ 2.51 × 10⁻⁴ H/m.

What has high permeability?

Ferromagnetic materials like iron, often with μr in the hundreds or thousands.
