This application simulates the movement of an electric charge in an electromagnetic field. It is possible to observe how electrical and magnetic forces act on an electrical charge. By the "examples" button, you can quickly access parameters that simulate circular, helical or cycloidal trajectories.

If you're on a touchscreen device, use the usual touchscreen gestures:

• One finger: moves the viewing angle.
• Two fingers, pinch gesture: zooms.
• Two fingers, swiping in the same direction: shifts the camera position.

Buttons:

• : Restarts the simulation.
• : Accesses the parameters and initial conditions of the system: initial angle, pendulum length, etc.

The dynamics of electric charge is given by the solution of the combination of Newton's second law with the Lorentz equation:

This ODE is solved by the fourth order Runge-Kutta method with time integration step $h$. We are disregarding the energy loss due to load acceleration.
