Construction and remote demonstration of an inexpensive but efficient experimental setup for studying self-inductance and mutual-inductance between two coils

Abstract

Measurement of self-inductance and mutual-inductance has been demonstrated as a laboratory experiment with great simplicity. The novelty of this demonstration lies in its straightforward circuitry and methodology, enabling the experiment accessible to students with minimal prerequisite knowledge. A coil-pair setup was constructed using discarded common household articles, costing very low but provides high quality throughput in teaching-learning experience. The demonstration can be easily conducted online using a laptop without the need of extra power supply. The experiment suits for high school and pre-university students, as evident by twenty first-semester undergraduate physics and electronics students who found it both satisfying and enjoyable with a relatively flat learning curve.
