The purpose of this part of IEC60404 is to define the method of measurement of the magnetic flux density, magnetic polarization and the magnetic field strength and also to determine the demagnetization curve and recoil line of permanent magnet materials, such as those specified in lEC60404‑8‑1 [1] 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 part of IEC60404 refer to the measurement of the magnetic properties in a closed magnetic circuit.
