In the present study, the measurements were carried out on the specimens of copper, aluminum, and stainless steel to determine the effect of coil shape and power source frequency on the levitation force by the use of small power oscillator (200W). By comparing the measured value with theoretical one which is derived by Fromm and Jehn, the following conclusions were obtained ; 1) Measured values of strength of magnetic field along the coil axis agree well with the calculated one derived from the assumption of the superposition of single coils. 2) Calculated levitation force indicates the semi-quantitative agreement with the observed value. For aluminum and stainless steel specimens the calculations give the values which are 20-30% smaller than that of observed values and for copper specimen it gives about 40% smaller value than the actual one. 3) In the experimental range (45 to 160 kHz), levitation force changes linearly with logarithm of frequency and observed dependency on frequency is about 10% larger that of theoretical.","subitem_description_type":"Abstract"}]},"item_4_description_41":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"紀要類(bulletin)","subitem_description_type":"Other"}]},"item_4_description_66":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"469928 bytes","subitem_description_type":"Other"}]},"item_4_full_name_2":{"attribute_name":"著者(ヨミ)","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"123093","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SHIRAISHI, Yutaka"}]},{"nameIdentifiers":[{"nameIdentifier":"123094","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SAITO, Tunezo"}]}]},"item_4_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東北大學選鉱製錬研究所"}]},"item_4_radio_69":{"attribute_name":"公開範囲","attribute_value_mlt":[{"subitem_radio_item":"学外"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0040876X","subitem_source_identifier_type":"ISSN"}]},"item_4_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00168425","subitem_source_identifier_type":"NCID"}]},"item_4_version_type_16":{"attribute_name":"著者版フラグ","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":"白石, 裕"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"斎藤,  恒三"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-20"}],"displaytype":"detail","filename":"KJ00000134891.pdf","filesize":[{"value":"469.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00000134891.pdf","url":"https://tohoku.repo.nii.ac.jp/record/50393/files/KJ00000134891.pdf"},"version_id":"24a32c0b-f736-4f88-bb76-118ae33f9457"}]},"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":"<報文>電磁浮揚の特性に関する基礎的研究その1 : 浮揚力について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"<報文>電磁浮揚の特性に関する基礎的研究その1 : 浮揚力について"}]},"item_type_id":"4","owner":"3","path":["292"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-05-02"},"publish_date":"2008-05-02","publish_status":"0","recid":"50393","relation_version_is_last":true,"title":["<報文>電磁浮揚の特性に関する基礎的研究その1 : 浮揚力について"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T15:20:08.399733+00:00"}
