Fafeicy Hand Crank Generator DIY Educational Physics Teaching Model for Middle & High School Students

MAIN PURPOSE: This instrument is used by schools to scientifically demonstrate the working principle of generator, demonstrating that mechanical energy can be converted into electrical energy. MATERIALS: The hand crank generator is made of excellent PVC and other materials, which has good toughness, high strength, large resistance, ensuring a longer service life. WORKING PRINCIPLE: The armature rotor is rotated in a permanent magnetic field to generate current. When the hand wheel rotates to drive the armature rotor, the current is generated in the coil to make the LED light. COMPOSITION PARTS: The instrument is composed of base, armature, pole shoe, magnetic field, brush, hand wheel, and load plate, etc., with a compact structure, easy connection and APPLICABLE SCENES: This hand generator is suitable for physics teaching in middle and high schools, DIY electronic experiments, etc., provides a clear and intuitive demonstration process.
