Title:
消磁システム、構造体、及び消磁方法
Document Type and Number:
Japanese Patent JP7013291
Kind Code:
B2
Abstract:
To provide a demagnetization system, structure, and demagnetization method, capable of more accurately performing demagnetization even when a magnetization state of the structure has changed.SOLUTION: A demagnetization system is to be applied to a structure 1 configured to include a magnetic member, the demagnetization system comprising: a demagnetization coil 3 for generating a magnetic field for canceling a magnetic field externally generated by the structure 1; a magnetic sensor 2 for measuring a variation in a vector value or intensity of the magnetic field generated by the structure 1; a cancel coil 4 for generating a magnetic field for canceling a magnetic field generated around an installation position of the magnetic sensor 2 by the demagnetization coil 3; and a control device 5 for controlling values of flowing current of the demagnetization coil 3 and the cancel coil 4. The control device 5 comprises a demagnetization coil current setting unit for setting a value of the flowing current of the demagnetization coil 3 on the basis of the variation in the vector value or intensity of the magnetic field measured by the magnetic sensor 2.SELECTED DRAWING: Figure 1
