3D Field of Cuboidal Magnet

Requires a Wolfram Notebook System
Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.
The field components ,
, and
of a permanent magnet with dimensions
,
,
and strength 1.4 Tesla are analytically calculated and displayed as a vector field.
