A Design of Automatic Magnetic Properties Measurement System for Under/Postgraduate Open Experimental Project: Effective, Low Cost, and Scalable

Contribution: This research designs an experimental education project of an automatic material magnetism properties measurement system. It explores how the do-it-yourself (DIY), hands-on establishment, and hardware–software integration experiment system could be leveraged to enhance the understanding of the electromagnetism theory and nonelectrical quantity measurement application. Background: Designing and establishing a prototype of an automatic measurement system are essential, inspiring and beneficial to comprehending and consolidating the theoretical principles and simulations in electromagnetism and nonelectrical quantity measurement technology courses. Furthermore, in the vision of batch deployment and flexible group teaching, a cost-efficiency, hard/soft integration system for the electromagnetism property measurement definitely fits the aim of innovation laboratory education. Intended Outcomes: This project is intended to guide the students to finish a comprehensive research-oriented project loop for multiple skills training. It is also intended to encourage student motivation and confidence through theory investigation, hands-on group collaboration, and tunning for performance calibration. Application Design: The design of the proposed project includes the literature review, hardware selection and assembly, system integration, software programming, interface visualization, and system performance calibration. The participants are assessed with both objective exam questions and subjective open survey for training objectives to reveal their increased knowledge, interests, skill confidence, and creative thinking. Findings: The proposed project has been used in 4-year laboratory open experiments with students at different levels from freshmen undergraduates to 1st-year postgraduates. A use case and survey assessment demonstrate tremendous knowledge, skills, and confidence improvement among students in electromagnetism and measurement technology courses.
