This disassemblable assembly is designed for handson verification of the relationship between armature steering and the direction of current and magnetic force lines. Its construction supports reinforcement with M3 and M4 screws and nuts to create a stable, solid structure that improves conversion performance during demonstrations and experiments. Key benefits Directly demonstrates how armature motion relates to current direction and magnetic force lines, supporting clear conceptual understanding. Modular design allows easy disassembly and reassembly for observation, measurement, and troubleshooting. Compatibility with M3 and M4 screws and nuts makes reinforcement simple and yields a more stable assembly during testing. Solid structural design reduces unwanted movement and supports better conversion performance in practical setups. Features Function: Allows verification of armature steering versus current and magnetic force lines through repeated assembly and testing. Compatibility: Supports M3 screws and nuts and M4 screws and nuts for reinforcement. Assembly: Can be taken apart and reassembled to examine internal relationships and to adjust components for experiments. Performance: Stable, solid structure intended to improve conversion behavior during demonstrations. Typical use scenarios Classroom demonstration: Use the assembly to show students how current direction and magnetic field orientation determine armature steering in electric motor principles. Laboratory experiment: Disassemble components to take measurements, change connections, and document the effect of current direction on magnetic forces. Hobbyist projects and prototyping: Reinforce the assembly with M3 or M4 fasteners to create a stable test rig for small motor experiments and iterative design work. Usage note Reinforce the structure with compatible M3 or M4 screws and nuts during assembly to maintain stability and consistent results. This product is a practical tool for educators, students, and hobbyists who need a clear, repeatable way to study the interaction between armature steering, current direction, and magnetic force lines.
