เครื่องกำเนิดไฟฟ้าด้วยมือ
Gelsonlab HSTM-042 Electric Generator DIY Science Kit for Kids education
เครื่องกำเนิดไฟฟ้าด้วยมือ 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.
