Magnetic susceptibility to relative permeability
Type a value in χm to get it in μr instantly.
4,001μr
That's about the same as electrical steel.
Convert the other way: μr to χm
What it means
How strongly does it gather field?
Figures for iron and alloys are typical maximum or initial values. Real permeability changes with field strength, frequency and temperature.
The math
How to convert χm to μr
Absolute permeability is μ = μr × 1.2566 μH/m, and susceptibility is χ = μr − 1.
Example: 4,000 χm = 4,001 μr.
