Title (EN) MAGNETIC MEASURING METHOD AND DEVICE
(FR) PROCÉDÉ ET DISPOSITIF DE MESURE MAGNÉTIQUE
(JA) 磁気測定方法および装置
Abstract: front page image
(EN)The local magnetic property of a magnetic material is measured with high precision and so as to be insusceptible to disturbance and so on, by direct-current magnetizing the magnetic material to a rotational magnetization region as well as alternating-current exciting the magnetic material in the direction having a component orthogonal to the direction of the direct-current magnetization, and measuring the component orthogonal to the direction of the direct-current magnetization in an alternating-current magnetic field produced by the interaction with the magnetic material.
(FR)L'invention concerne un procédé de mesure très précise de la propriété magnétique locale d'une matière magnétique de sorte que celle-ci soit insensible à des perturbations et analogue, qui comporte les étapes consistant à: magnétiser par un courant continu la matière magnétique vers une région de magnétisation rotative et exciter la matière magnétique par un courant alternatif dans une direction comportant un composant orthogonal par rapport à la direction de magnétisation en courant continu; et mesurer le composant orthogonal à la direction de magnétisation par courant continu dans un champ magnétique en courant alternatif produit par l'interaction avec la matière magnétique.
(JA)磁性材料を回転磁化領域まで直流磁化するとともに、該直流磁化の方向と直交する成分をもつ方向に交流励磁を行い、前記磁性材料との相互作用により生じる交流磁場の内、前記直流磁化の方向と直交する成分を測定することにより、磁性材料の局所的な磁気特性を、高精度で、かつ外乱などの影響を受けにくいように測定する。
