About This

• 1. This practical DIY DC motor demonstrator intuitively presents the core physical phenomenon of Ampere force, vividly verifying the mechanical motion effect generated when energized conductors work in a magnetic field, making abstract electromagnetic theories more intuitive and understandable.
• 2. The experiment set fully demonstrates the standard electromagnetic left-hand rule, allowing users to master the professional judgment logic of magnetic field direction, current direction and conductor stress direction through hands-on operation and observation.
• 3. Featuring simple assembly and obvious experimental effects, this equipment helps users sort out electromagnetic operating rules, effectively improving practical operation proficiency and physical principle cognition ability.
• 4. Support contrastive verification experiments by adjusting magnetic field direction and battery current direction; the forward and reverse rotation changes of the motor clearly show the correlation between current, magnetic field and Ampere force.
• 5. Compact integrated structural design enables convenient assembly and debugging, serving as ideal auxiliary teaching equipment for electromagnetic principle demonstration and physical laboratory exploratory research.
