The purpose of this part of IEC 404 is to define the method of measurement of the
magnetic flux density, magnetic polarization and the magnetic field strength and also the
determination of the demagnetization curve and recoil line of permanent magnet materials,
such as those specified in IEC 404-8-1, the properties of which are presumed
homogeneous throughout their volume.
The performance of a magnetic system is not only dependent on the properties of the
permanent magnet material but also on the dimensions of the system, the air-gap and
other elements of the magnetic circuit. The methods described in this standard refer to the
measurement of the magnetic properties in a closed magnetic circuit simulating a ring.
