The Asia-Pacific Symposium on Applied Electromagnetics and Mechanics (APSAEM 2024) will take place at the UTeM, in Melaka, Malaysia from July 16 to 19, 2024. APSAEM2024 is the tenth symposium devoted to topics on electromagnetic phenomena, both low and high frequencies, and applications in electrical, mechanical, and communication systems. Due to COVID-19, it has been six years since the last APSAEM2018 . We had four presentations

1) Keynote Speech:

Magnetostriction and its Application to Engineering Devices

Prof. Emeritus Hiroyuki Wakiwaka (Shinshu University, Japan)

2) Paper1:

Magnetization of Magnetic Pipe Using Two C-Shaped Permanent Magnets for Monitoring Pipe Wall Thickness

K. Tashiro, K. Ishikawa, H. Wakiwaka (Shinshu University)

3) Paper22:

Investigation of Composite Material Discrimination Using Coil Impedance Characteristics Based on Machine Learning

K. Tsukadaira, K. Tashiro, H. Wakiwaka (Shinshu University), S. Saito, K. Machida, Y. Nakamura (Fuji Electric Co., Ltd.)

4) Paper4:

Angle Error Evaluation of Vernier Pattern Angle Sensor with Discrete Fourier Transform

Y. Kazekami, K. Tashiro, H. Wakiwaka (Shinshu University),
K. Masaki (Sensor Labo), M. Nirei (National Institute of Technology, Nagano College) and S. Kanazawa(Zawamaru)

It is our pleasure that the keynote speech will be given by Wakiwaka-sensei and Hisam-sensei. It will be a year since we last met in Nagano. Paper1 relates magnetic flux leakage testing, which is widely recognized techniquqe in the safety inspection of oil and gas pipelines. In this paper, our unique magnetization process is explained using FEM results. Paper 2 is a corporative research with Fuji Electric Co., Ltd as presented in the last APSAEM2018. In this paper, discrimination of Cupronikel plate and Cupronikel-Nickel-Cupronickel composite plate was successfully demonstrated. Paper4 is a corporative reseach with Dr. Masaki, Prof. Nirei and Mr. Kanazawa. In this paper, angle error in our proposed angle sensor was evaluated with DFT.
