Measurement Technologies for Permanent Magnets

S. Möwius, N. Kropff, M. Velicescu
Abstract:
Permanent magnets have wide applications in all important fields of our modern technology; they became indispensable in automotive industry, aerospace, acoustic, telecommunications, energy generation and in many more. Physically the permanent magnets are metastable systems. Fluctuations in the composition and of the processing parameters can cause fluctuations of the magnet properties. To obtain the optimal performances of their applications, the users are requiring careful controlling of non-machined parts as well as of the finished machined magnets. In most of the cases, measurement records of the final control of the assembled magnetic systems have to be performed. The aim of this paper is to review most typical measuring methods used for the magnetic properties of the permanent magnets, to comment their advantages and their limits and to discuss the accuracy which can be achieved.
