Vector Potential Lab helps you study magnetic fields through clear, hands-on tools. Pick a wire, loop, toroid, or moving charge and see how the vector potential behaves. Switch gauges, link potential to the magnetic field, and compare simple and advanced models. Change sizes, distances, and frequency to test real cases. The app is made for quick checks, homework help, and research ideas. No heavy math is required to get insight. Clean screens, fast results, and helpful notes guide you at each step. Learn faster and build stronger intuition about magnetic systems.
