Nonlinear magnet described by a spline - Transversal relative permeability

Hello,

I have a magnetisation curve for my material and wanted to make it in Flux by the option: nonlinear magnet decribed by a spline.

There I have to specify the 'Transversal relative permeability'. What is this? And what value makes sense? What does it mean if it's equal to 1?

Thank you in advance.

Hello,

In the case of nonlinear magnets, the value of the permeability it is not the same thing in both axis (x and y axis), the value of the axis parallel to magnetization is different from the value of the other axis.

A link to see how we calculate the transversal relative permeability:
