PROBLEM TO BE SOLVED: To provide a demagnetizer which can reduce the time and effort for switching the number of turns of a demagnetizing coil.SOLUTION: A demagnetizer 100 comprises: demagnetizing coils 30a-30c equipped to a hull 1; power supply units 20a-20c supplying power to each of the demagnetizing coils 30a-30c; and a control unit 10. The control unit 10 obtains the magnetomotive force of the demagnetizing coils 30a-30c required to cancel the magnetic field by the magnetism of the hull 1 and determines the number of turns of each of the demagnetizing coils 30a-30c on the basis of the magnetomotive force. The power supply units 20a-20c switch respectively from the number of turns of the demagnetizing coils 30a-30c to the number of turns determined by the control unit 10.SELECTED DRAWING: Figure 2

    【課題】消磁コイルの巻き数の切り替えにかかる手間を軽減できる消磁装置を提供する。【解決手段】消磁装置100は、船体1に装備された消磁コイル30a〜30cと、消磁コイル30a〜30cに電力をそれぞれ供給する電源装置20a〜20cと、制御装置10とを備える。制御装置10は、船体1の磁気による磁界を打ち消すために必要な消磁コイル30a〜30cの起磁力を取得し、当該起磁力に基づいて消磁コイル30a〜30cの巻き数をそれぞれ決定する。電源装置20a〜20cは、消磁コイル30a〜30cの巻き数を、制御装置10により決定された巻き数にそれぞれ切り替える。【選択図】図2
