PROBLEM TO BE SOLVED: To provide a magnetic pulse generation coil which is available for a long time by preventing a temperature of the magnetic pulse generation coil from rising by Joule heat that is generated with continuous electrification of a large pulse current, the magnetic pulse generation coil being configured to generate pulse-like magnetism.SOLUTION: A coil 2 for power generation is disposed in such a manner that a magnetic flux generated by a magnetic pulse generation coil 1 partially passes the coil for power generation. An electromotive force is induced in the coil for power generation by a magnetic flux change with magnetic pulse generation. A cooling fan 5 is rotated by using the electromotive force as power, such that the magnetic pulse generation coil is cooled.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】パルス状の磁気を発生する磁気パルス発生コイルにおいて、連続的なパルス大電流の通電にともない発生するジュール熱による磁気パルス発生コイルの昇温を抑制し、長時間の使用を可能にするコイルを提供する。【解決手段】磁気パルス発生コイル1の発生する磁束の一部が発電用コイル2を通過する様、発電用コイルを配置し、磁気パルス発生にともなう磁束変化により、発電用コイルに起電力を誘起し、この起電力を電力として用いて冷却ファン5を回転させることにより、磁気パルス発生コイルを冷却する。【選択図】図1
