Designed for middle and high school physics demonstrations and electronic experiments, this hand crank generator presents complex concepts with a clear, intuitive demonstration process. Key benefits - Scientific demonstration: shows how mechanical energy is converted into electrical energy, serving as an effective instructional tool in schools. - Efficient operation: when the handwheel is rotated, the armature rotor turns in a permanent magnetic field to generate current that lights the LED, providing a practical demonstration of generation. - Compact and user-friendly: built with a base, armature, pole shoe, magnetic field, brush, handwheel, and load plate. Its compact structure allows easy connections and comfortable bench-top use. What you get and how it works - The unit is designed to be straightforward to set up and operate, with all essential components integrated for hands-on learning and repeatable demonstrations. Use scenarios - In-class demonstrations to illustrate energy conversion and electromagnetic induction. - Student labs to explore how rotation speed or load affects generated voltage and LED brightness. - STEM projects, science fairs, or tutoring sessions requiring a portable, easy-to-use generator demonstration.
