Coulomb's Law
This interactive simulator explores Coulomb's Law in Electricity & Magnetism. Two charges with adjustable magnitude and distance. Force vectors shown. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.
Who it's for: Suited to beginners and first exposure to the topic. Typical context: Electricity & Magnetism.

How it works
The magnitude of the electrostatic force between two point charges in vacuum is F = k|q₁q₂|/r² with k ≈ 8.99×10⁹ N·m²/C². Like charges repel, unlike attract.
