A cylindrical rod in linear differeantial transformer and a circular shaped or semi-toroidal core in angular displacement transducer form the opened magnetic path, and naturally self-demagnetizing force exists in these cores. The effect of the self-demagnetizing force and the demagnetizing factor at the circular shaped core in the angular displacement transducer has not yet been discussed up to the present. Empirical formulae on the self-demag-netizing force and the demagnetizing factor at the circular shaped core are described in this paper. The comparatively small value between 1.0 and 12.0 was selected as a dimensional ratio from the practical demands. It has become clear that the value of the demagnetizing factors at the circular shaped cores are some twenty or thirty per cent smaller than that of the cylindrical rods obtained by R. M. Bozorth and some others. Especially, the demagnetizing factor of the core with air gap angle of 10 degrees at the center of the ring core is about fifty per cent smaller than that of the cylindrical rod for same dimensional ratio. It is well-known that the demagnetizing factor, ν, of the ring core with air gap of angle, θg, at the center of the ring core is given simply by ν = θg/360, if θg is in degrees. For the circular shaped core, however, which has comparatively small value of the dimensional ratio, the above equation except a few angle θg is not obtained the satisfactory coincidence with an experimental results. The self-demagnetizing force and demagnetizing factor of the cut-core which has very small air gap are also discussed in this paper.","subitem_description_type":"Abstract"}]},"item_10_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_10_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"信州大学工学部紀要 21: 79-94 (1966)","subitem_description_type":"Other"}]},"item_10_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"信州大学工学部"}]},"item_10_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0037-3818","subitem_source_identifier_type":"ISSN"}]},"item_10_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00121228","subitem_source_identifier_type":"NCID"}]},"item_1627890569677":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山田,  一","creatorNameLang":"ja"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-28"}],"displaytype":"detail","filename":"Engineering21-06.pdf","filesize":[{"value":"770.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Engineering21-06.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/13087/files/Engineering21-06.pdf"},"version_id":"ebc290f4-a4a7-42ac-8c91-2bb608033851"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"交流磁化による円弧状磁心の反磁界","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"交流磁化による円弧状磁心の反磁界","subitem_title_language":"ja"},{"subitem_title":"Demagnetizing Factors of Circular Shaped Cores by Sinusoidal Current Condition","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["1286"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-03-30"},"publish_date":"2009-03-30","publish_status":"0","recid":"13087","relation_version_is_last":true,"title":["交流磁化による円弧状磁心の反磁界"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-03-16T05:05:26.349085+00:00"}
