This interactive electric field simulator lets students place, drag, and adjust positive and negative point charges on a canvas to visualize how electric field lines form, curve, and interact in real time. Through three guided activities—exploring single-charge field patterns, investigating dipole configurations, and discovering the fundamental rules governing field lines—students build an intuitive, hands-on understanding of core electrostatics concepts such as field direction, field strength, and the principle that field lines never cross.
The activity is rounded out with key conceptual summaries (Coulomb’s Law, electric field, and electric potential) and a five-question true/false quiz to check understanding, making it a self-contained tool for both inquiry-based exploration.
Here is a fully editable companion worksheet and its answer key.
