Abstract:

Hysteresis loop tracing (HLT) experiment is an undergraduate experiment for physics and engineering students to demonstrate magnetic properties of ferrite materials. In this paper, we explore a new approach of setting- up triggered testing of magnetic hysteresis via a remotely controlled loop tracer. To aid student learners, through an experimental design, we focused on factors such as analytical expression of mathematical model and modeling of reversible changes, which were crucial for learning hysteresis components. The goal was to study the phenomena of magnetic hysteresis and to calculate the retentivity, coercivity and saturation magnetization of a material using a hybrid model including simulation and remotely controlled hysteresis loop tracer. The remotely controlled equipment allowed recording the applied magnetic field (H) from an internet-enabled computer. To analyze learning experiences using online laboratories, we evaluated usage of online experiment among engineering students (N=200) by organized hands-on workshops and direct feedback collection. We found students adapted to use simulations and remotely controlled lab equipment augmenting laboratory skills, equipment accessibility and blended learning experiences.
