Observer Frames and Field Geometry: A Visual and Intuitive Analysis in Relativistic Electrodynamics

This paper presents a visual and geometric framework for understanding how length contraction gives rise to relativistic magnetic fields across observer frames. By demonstrating how spatial length contraction disrupts field symmetry, we establish a transformation between electric divergence and magnetic curl Using a first-principles angular sightline model, this work visualizes spatial contraction along the axis of motion, showing how relativistic transverse field compression generates non-zero magnetic curl without relying strictly on abstract four-vector formalisms. This model provides an intuitive, geometric bridge between electrostatics and unified electrodynamics.
