Electromagnetic Field Visualization Around a Long Straight Conductor using MATLAB GUI

This MATLAB GUI-based application enables visualization of electromagnetic fields around long straight conductors. The program provides an efficient approach to understanding electromagnetic field distribution patterns through interactive parameter adjustments. Key computational methods include numerical solutions of Maxwell's equations using vector potential formulations, with real-time field line tracing algorithms. The interface incorporates sliders for current magnitude and observation distance controls, while implementing Biot-Savart law calculations for magnetic field components and Coulomb's law for electric field simulations. Users can modify parameters such as wire length, current intensity, and observation plane distance to dynamically observe field variations. The GUI architecture employs MATLAB's App Designer framework, utilizing callback functions for seamless parameter updates and field recomputation. No advanced programming expertise is required - the intuitive interface allows immediate operation through interactive controls. Both students and professionals can benefit from this tool for studying electromagnetic phenomena, with features including field strength visualization, direction indicators, and customizable display options. The program serves as an effective educational resource for exploring fundamental electromagnetic principles through practical visualization techniques.
