Please download plugin and scene below to visualize current vector field using trueSpace7.61 Beta. This video illustrates how to install plugin and load the scene in the trueSpace. You have to install trueSpace 7.61B8 (free) (workspace only is enough) to try plugin.
Please use the following links to download.
Figure 1: Unnormalized current vector field
Figure 2: Normalized current vector field
We got following angular momentum components for this example
= -0.248 ħ
= 0.248 ħ
= 0.356 ħ
Please refer to chapter 1 of the book for detailed discussion of the topic and related subject.
