Interactive Electric Field of few point charges with Matplotlib Widgets
Second part of the videolesson about plotting Electric Field with Python is dedicated to creating interactive features to the Electric Field Plot. These real time control features are allowed to modify positions of all point charges, value of the charges and some displaying properties, like line density and field type. Everything was coded with Matplotlib Widgets (Sliders, Radiobuttons and Checkbuttons) in Python
