We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi Jan, 

The Relative Permeability is the real part of the complex relative permeability. 

Magntic loss tangent is the ratio of imag/real of the complex permbeality. Note that the sign of loss tangent should be positive to represent the loss.
