- Accordingly, the magnetic fields which a ferromagnetic material produces after demagnetization need to be separated into two field components, which are by the remnant magnetization and by the induced magnetization due to earth magnetic field, respectively [6]. In addition, each field component should be decomposed into two directional components which are the same directions as the longitudinal and the vertical directions of earth magnetic field, respectively This study was made in the view of navy magnetic treatment technology for vessels and submarines as one of magnetic applications and deals with the effects of the longitudinal and the vertical bias fields on the magnitude and the direction of the remnant magnetization after demagnetization.
- In evaluating the remnant magnetization of the sample, the measured magnetic fields should be separated into HILM and HPLM, HIVM, HPVM, where HILM is a magnetic field by magnetization due to the horizontal component of earth magnetic field and HPLM is the one by the horizontal component of remnant magnetization, HIVM is the one by magnetization due to the vertical component of earth magnetic field and HPVM is the one by the vertical component of the remnant magnetization, respectively. Therefore, HLM becomes the sum of HILM and HPLM and also HVM is the sum of HIVM and HPVM.
대상 데이터
- The demagnetization was done again after pre-demagnetization with the first pulse of 15 kA/m. The tube-shaped sample used in this experiment was made of a galvanized steel sheet with the thickness of 0.16 mm. The length and the diameter of the tube sample were 100 mm and 60 mm, respectively.
