| Title | Magnetic materials - Part 14: Methods of measurement of the magnetic dipole moment of a ferromagnetic material specimen by the withdrawal or rotation method |
| Project Number | 14041 |
| Abstract/Scope | Applicable to all ferromagnetic materials. It is particularly aimed at the measurement of the magnetic dipole moment of permanent magnet (magnetically hard) materials and the measurement of the specific saturation magnetic polarization of cemented carbide materials having a ferromagnetic binder. To describe the general principles of the determination of the magnetic dipole moment of a ferromagnetic material specimen using a detection coil in an open magnetic circuit. By including a means of magnetizing the material to saturation, the saturation magnetic dipole moment can also be determined. In addition, the average magnetic polarization of a test specimen can be derived from the measurement of its magnetic dipole moment and volume. The calibration of magnetic moment coil systems and the measurement of the magnetic dipole moment of feebly magnetic materials can also be determined using this method. Measurements are normally performed at room temperature but measurements at other temperatures can be conducted by heating or cooling the volume occupied by the test specimen within the detection coil. The measurement of remanence, coercivity, maximum energy product and other parameters can be made in a closed magnetic circuit as described in EN 60404-4 and EN 60404-5. Measurement of the coercivity HcJ of soft and semi-hard materials can also be performed in an open circuit as described in EN 60404-7. |

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved
(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat
(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level
(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement
(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
