The outer matte-green housing remains completely stationary while a purple internal support frame rigidly suspends a yellow rectangular electromagnetic core at the center. Inside the core are two precision-wound copper electromagnetic coils mounted on opposing sides of a central moving armature. As electrical current is applied to the left coil, an intense magnetic field is generated that attracts or repels the internal steel or permanent-magnet armature, causing the blue piston shaft to accelerate smoothly toward the right. Once the piston reaches the end of its stroke, the left coil de-energizes while the right coil immediately energizes, reversing the magnetic field and driving the piston back toward the left. This alternating sequence repeats continuously, creating a smooth, high-speed reciprocating motion with no crankshaft, converting electrical energy directly into precise linear mechanical motion. The animation should visualize glowing magnetic field lines, flowing electrical current through the copper windings, subtle heat shimmer from energized coils, and smooth, vibration-free piston movement. Include semi-transparent cutaway views so the viewer can clearly observe the internal electromagnetic interactions, moving armature, guide shafts, bearings, and structural supports. Render the animation in an ultra-realistic CAD engineering style with photorealistic materials, polished machined metal, anodized components, realistic reflections, studio lighting, ambient occlusion, and exploded-view transitions that reveal exactly how the actuator functions internally.
