Educational software for the numerical correction of experimental magnetization curves

摘要

The proposed software allows students to get aware of the importance of the experimental data accuracy in magnetism. A common error source for the magnetization curves (including hysteresis cycles) is the demagnetization effect and the influence of the magnetic sensor position. Our software helps the user to understand the principle and the effect of each correction method. The Graphical User Interface (GUI) is designed as a wizard, assisting students to decide which the best correction procedure could be and to obtain the intrinsic magnetic material characteristic to be used in electromagnetic field computation.
