Plotting Electric Fields with Line Integral Convolution
Requires a Wolfram Notebook System
Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.
Several configurations of charges are plotted using the line integral convolution algorithm. In each case, it is possible to observe different charateristics of the fields. Bands of the same color stand for equipotential curves. Try to recognize whether they are positive or negative and determine their relative sizes.
