Abstract

IEC 60404-18:2025 defines the general principle and technical details of the methods of measurement of the DC magnetic properties of permanent magnet materials in an open magnetic circuit using a superconducting magnet (SCM).This method is applicable to permanent magnet materials, such as those specified in IEC 60404‑8‑1, the properties of which are presumed homogeneous throughout their volume.There are two methods:- the SCM-vibrating sample magnetometer (VSM) method;- the SCM-extraction method.This document also specifies methods to correct the influence of the self-demagnetizing field in the test specimen on the demagnetization curve obtained in an open magnetic circuit. The magnetic properties are determined from the corrected demagnetization curve.
