Electric Field Explorer vs Ladybug ABC

E-Field Explorer makes electric fields visible and intuitive. Place positive and negative charges directly on the field, move them freely, and watch field lines, equipotential lines, and field strength update in real time. Use preset scenes such as a single charge, dipole, quadrupole, capacitor, or hollow sphere for a quick start, then adapt each setup to your own experiment. You can adjust charge strength for selected charges and optionally show labels for clearer orientation. The integrated particle emitter makes field behavior especially easy to grasp. Choose positive or negative test charges, automatic emission or single pulses, and damped or undamped motion. That makes the app ideal for teaching, self-study, and visual demonstrations on iPhone and iPad. Features: - Place positive and negative charges with drag and drop - Toggle field lines, equipotential lines, and heatmap - Adjust the strength of individual charges - Start from preset scenes for common electrostatic setups - Share screenshots directly from the app
