Oct 30, 2020 · I have also started with a small program like this, using Matplotlib for visualization. But with increasing complexity, Matplotlib has gotten way too slow, and I switched over to VisPy which has OpenGL support. Now, very recently I released a full-fledged Python-powered GUI for magnetic field calculation of arbitrary loops of wire.

Here's my code so far, with the not-so-promising 3D quiver approach: import numpy as np import matplotlib.pyplot as plt import mpl_toolkits.mplot3d.axes3d ax1 = plt.subplot(111,projection='3d') t = np.linspace(0,10,40) y = np.sin(t) z = np.sin(t) line, = ax1.plot(t,y,z,color='r',lw=2) ax1.quiver(t,y,z, t*0,y,z)

A quiver plot is a type of 2D plot that shows vector lines as arrows. Quiver plots are useful in electrical engineering to visualize electrical potential and valuable in mechanical engineering to show stress gradients. To create the quiver plots, we'll use Python, matplotlib, numpy and a Jupyter notebook.

Call signature:: quiverkey (Q, X, Y, U, label, ** kw) Arguments: * Q *: The Quiver instance returned by a call to quiver.
When plotting 3D arrows, there are no arguments in Axes3D.quiver() that can be used to changed the shape/size of the head of a 3D arrow. Nor is there any related attribute in Line3DCollection that can be used. The size of a 3D arrow head seems to be dependent on the scale of the plot, i.e., xlim, ylim, and zlim.
