&MAGNETIC


COMPONENTS

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.)


OPTIONS

There are no local options in this section, but the OPTIONS command can be used for global options, see the top level OPTIONS command.

SUSCEPTIBILITY

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
