Field changes
-
Field created at the surface when extrapolated
to higher z is of similar form (see later)
-
Further from the surface the function
smears and smoothes
out
-
The average total field decreases
as field lines join up
-
Vertical scale is indication of total
positive field
-
Horizontal scale gives us distance
from z = 0 in pixels
-
For scale, my arrays have 512 x 512
pixels
-
Graph appears to show an exponential
fall-off
