| description | To provide a split type ring-shaped magnetic material for noise countermeasure which has been difficult to be produced with Fe-based nanocrystalline alloys, and obtain an excellent noise reduction effect.SOLUTION: A ring-shaped magnetic material for noise countermeasure includes a soft magnetic metal thin ribbon laminated along a radial direction, and is used by inserting a cable therein. The ring-shaped magnetic material for noise countermeasure includes a plurality of split pieces which are divided in a non-annular shape and are used in a ring-shape by contacting split surfaces of the split pieces with one another, and the product FL×Hc of the flatness FL of the spit surface and the coercive force Hc of the split piece is equal to 7.0 μmA/m or less. Here, the flatness FL is the sum of the absolute values of the maximum and minimum values of a cross-sectional curve measured according to JIS B 0601:2001.SELECTED DRAWING: Figure 2
【課題】Ｆｅ基ナノ結晶合金では作製が困難であった分割型のノイズ対策用環状磁性体を提供し、優れたノイズ低減効果を得ること。【解決手段】径方向に沿って積層された軟磁性金属薄帯を含み、内側にケーブルを挿通させて用いる、ノイズ対策用環状磁性体であって、前記ノイズ対策用環状磁性体は、非環状に分割された複数の分割片からなり、該分割片の分割面同士を当接させて環状として用い、前記分割面の平面度ＦＬと前記分割片の保磁力Ｈｃとの積ＦＬ×Ｈｃが７．０μｍ・Ａ／ｍ以下である、ノイズ対策用環状磁性体。ここで、前記平面度ＦＬは、JIS B 0601:2001に準拠して測定した断面曲線の最大値及び最小値の絶対値の和である。【選択図】図２ |
