Simulation of electron motion in electric and magnetic fields using scratch
The movement of electrons in electric fields and magnetic fields are difficult to observe. One technique in observing the movement of electrons is by numerical solutions and displayed electron trajectories in the computer. To draw electron trajectories in the electric fields and magnetic fields, we use software Scratch. We chose to use Scratch because Scratch is freeware and easy to use. In this research, we used two methods. This is an analytical and numerical method. The result compared analytical methods and Runge-Kutta method, we get accurate of Runge-Kutta methods for trajectory in the y-axis is 99.9995 % and 99.98199 % for trajectory in the z-axis. This shows that Scratch can be used to help to the model mathematical equation in complex physics case.
