Hand Crank Generator for School Physics Demonstration, Educational Experiment Model

Hand Crank Generator for Physics Teaching This hand crank generator is a practical teaching instrument designed for school science demonstrations. It clearly shows how mechanical energy can be converted into electrical energy, making the working principle of a generator easy for students to understand and observe in a classroom setting. How It Works The generator uses an armature rotor that spins within a permanent magnetic field to produce current. As the hand wheel is turned, the armature rotates and a current is generated in the coil, causing the connected LED light to illuminate. The two ends of the armature coil are linked to copper rings, which form the collection and reversing mechanism. This complete process, from turning the hand wheel to the LED lighting up, makes the principle of power generation visual and intuitive for learners. Thoughtful Construction for Classroom Use The instrument is made from PVC, offering good toughness and strength to withstand repeated handling and the occasional knock during lessons. Its compact structure is composed of clearly identifiable parts, including the base, armature, pole shoe, magnetic field, brush, hand wheel and load plate. The simple design requires no complicated assembly, so teachers and students can begin using it quickly and save valuable preparation time. What's Included 1 x Hand Crank Generator
