| contents | We have created a simple, portable, low-cost setup allowing the students and teachers to experiment with and discuss electromagnetic induction in a safe way, using low currents. The simplicity and portability make these activities well suited for experiments outside of the classroom, which is particularly welcome for distance learning. The setup consists of two smartphones used as signal generators, a small coil, two loudspeakers connected to the coil and a third smartphone used as an oscilloscope. We have no doubt that simple, low cost, portable experiments using engaging elements such as smartphones, sound, and music, will be attractive for secondary school and first-year university physics courses. |
