Title: Magnetic characteristic measuring method of soft magnetic material
Inventor: YABUMOTO MASAO
IPC: G01R33/12
Filed: 1988-10-12
Abstract: PURPOSE:To improve accuracy when a sample having a small cross sectional area is measured and under a relatively low exciting condition by providing an amplifier having a variable amplification ratio thereby to automatically control the amplification ratio. CONSTITUTION:An amplifier which can vary its amplification ratio is placed between a magnetic flux detecting coil, a magnetic field detecting coil or an exciting current shunt and its detector. The amplification ratio is automatically controlled such that an output voltage of the amplifier is within 50-100% of the input voltage range of the detector. At an early stage of measurement, an applying voltage to the exciting coil which satisfies predetermined setting conditions for excitation is learned from the correlation among the applying voltage to the exciting coil, magnetic flux density and magnetic field strength. After demagnetization, the learned exciting voltage is used for setting. Thereafter, magnetic characteristic is measured.
