Electric and Magnetic Fields

Build one coherent electromagnetic model from charge conservation and Coulomb force to magnetic-field direction rules, Lorentz forces, electric potential, and equipotential-field geometry.

Physics HL, chapter 18. 1 simulations.

Simulation: Electric Superposition Map

Adjust two source charges and inspect field vectors, potential, and force on a movable test charge in real time.
