Abstract
The topic of electric and magnetic fields is fundamental to the physics curriculum in both high school and college. The applied aspect of this topic has triggered the rapid development of modern technology in this era. This paper reported a remote data acquisition system developed for experiments with magnetic fields by coils to support experimental physics learning remotely. The system used magnetic sensors, Arduino interfaces, and NI-Vernier Sensor-DAQ and LabVIEW as a data acquisition software. It was successful in testing for and measuring the distribution of magnetic fields along the axis of a circular coil. The measurement results showed experimental values in line with Biot–Savart law. The system developed is therefore useful as a learning tool that provides students with the opportunity to control instruments and conduct experiments in real-time remotely via the web. This system is also useful for overcoming the limited access to experimental devices.
