Traceable measurement of soft magnetic materials at high frequencies

Whilst written EN standards already exist for traceable magnetic measuremen ts at low and medium frequencies, extending these to frequencies up to 100 kHz and higher requires rigorous investigation of various additional factor s. These are considered in this paper and results showing the importance of the winding configuration and the difficulty in defining the temperature o f measurement presented.
