Abstract	The permeability of magnetic materials determines the inductance value of chokes and transformers. Upon introducing new materials, the permeability μr of the magnetic material has to be determined. Up to now, the permeability has been determined using an Epstein frame. However, if a planar shape of a magnetic core is under investigation, the mentioned measurement set-up is not applicable. The aim of this paper is present a new method to determine the permeability of planar shaped magnetic cores used in printed circuit boards integrated planar coils. Here, reference simulations were combined with measurements, whereby all results where in good agreement. In conclusion, this newly presented setup is easy to construct and can be universally applied to determine the permeability of e.g. ferrite polymer compound cores.
