مولد كهربائي يدوي
مولد كهربائي Gelsonlab HSTM-042 لتعليم الأطفال
مولد كهربائي يدوي is an experimental device for generating current by turning the handle and accelerating the gear set to drive the coil to cut the magnetic line of force. Through experiments, we can understand the principle of converting mechanical energy into electrical energy and the relationship between electromagnetism.
