Develop a Framework of Ferro-Magnetization Sensor on Weightlessness in Modified Bessel Analysis

A framework of ferro-magnetization on apparent weightiness, through electro-magnetic induction, is proposed in this study. Here the integral solution of ferro-magnetization, based on Boltzmann probabilistic theory in modified Bessel function, avoids unstable result accessed from traditional Langevin’s analysis. Also, a self-designed electromagnetism mechanism measuring gravitational counteraction of testing sample is set up and used to evaluate its magnetic behavior on apparent weight. That not only features as a simple device with economical cost and easy operation, but also could be further extended to the application of ferro-magnetization sensor. While compared to the results measured from Vibration Sample Magnetometer (VSM) for ferro-product provided by Matsumoto co., magnetization curve of self-prepared ferro-sample, base on present measuring method, shows an excellent agreement within the working region of 0~36 mT , in which the maximum relative error 100 %, evaluated from traditional classic Langevin theorem, could be remarkably reduced to 20 %.
