Matplotlib provee una función llamada streamplot, para crear flujos que puede usarse para representar vectores de campo. El código python muestra la representación de un campo eléctrico a partir de multiples cargas. Las multiples cargas son seleccionadas como potencia de 2 (1 dipolo, 2 cuadrupolo, etc). Details. The Liénard–Wiechert scalar potential is given by where is the electron charge, is the velocity vector, and is the distance from the current position to the original position at the retarded time .

May 07, 2019 · The 3D plotting functions are quite intuitive: instead of just scatter we call scatter3D, and instead of passing only x and y data, we pass over x, y, and z. All of the other function settings such as colour and line type remain the same as with the 2D plotting functions. Here’s an example of plotting a 3D line and 3D points.
