Details

Reference [1] computes the three components of the magnetic field, , , and , for a cuboidal permanent magnet. This Demonstration shows the level surfaces colored red, blue, green for , , , respectively, and starting at the mid-plane for each component.

The controls available are:

, , change the magnet dimensions

cut the graph at a value

level range

, , toggle to display , , and components

high double the graphics calculation grid
