Summary:

Abstract

Purpose

This paper aims to show a low-cost and easy to use measurement method for characterizing magnetic material B(H) relation up to medium frequencies providing an acceptable overall accuracy of the acquired data.

Design/methodology/approach

Saturation fields at MHz frequencies are obtained through resonance effects of properly designed circuit. Simulations and measurements are presented and discussed.

Findings

The paper shows the flexibility of the method and the possibility to use it for a complete characterization of the magnetic cores. Discussions and possible extension to rotating field measurements are reported.

Originality/value

The paper provides information on a low-cost and easy to use measurement method to characterize magnetic hysteretic materials.
