&MAGNETIC
Sets the x, y and z components of the magnetic field. The default unit
is the rather unconventional 100 Gauss which does however fit in the
overall system of units used by Garfield. You may also use Gauss or Tesla
if you prefer.
If your cell has been entered in polar coordinates, you should ensure
that both the x and the y components are zero. Only the z component
may be non-zero in this case.
Format:
COMPONENTS Bx By Bz [GAUSS | TESLA]
Examples:
COMP 0 0 50
COMP 0 0 5000 G
COMP 0 0 0.5 T
(All three are equivalent.)
There are no local options in this section, but the OPTIONS command
can be used for global options, see the top level OPTIONS command.
Sets the susceptibility of the gas and the wires. The unit system
is irrelevant: only the ratio matters. The default settings are 1
for the wires and 0 for the gas. The magnetic field has no effect
if the two susceptibilities are equal.
Format:
SUSCEPTIBILITY susc_wire susc_gas
Example:
SUSC 1 0
