Gaya Gerak Listrik Induksi (Hk. Faraday) | Fisika XII

Summary

In this educational demonstration, students learn about the relationship between electricity and magnetism. The presenter uses a coil connected to a galvanometer and a magnet to show how moving the magnet around the coil generates electricity, illustrated by the galvanometer's needle movement. The experiment clearly demonstrates that electricity can be produced from a magnetic field through the motion of a magnet near a coil, emphasizing the principle of electromagnetic induction. This engaging experiment aims to enhance understanding of the generation of electricity and the concept of induced electromotive force (GGL).
