Magnetic field component.
Author: Erik B Knudsen, Peter Christiansen, and Peter Willendrup
Origin: RISOE
Date: August 2006
End of magnetic field region defined by the latest preceeding Pol_Bfield component.
The component is concentric. It means that it requires a
// START MAGNETIC FIELD COMPONENT msf =
Pol_Bfield(xw=0.08, yh=0.08, length=0.2, Bx=0, By=-0.678332e-4, Bz=0)
AT (0, 0, 0) RELATIVE armMSF
// HERE CAN BE OTHER COMPONENTS INSIDE THE MAGNETIC FIELD
// STOP MAGNETIC FIELD COMPONENT msfCp = Pol_Bfield_stop() AT ("SOMEWHERE") RELATIVE armMSF
In between the two components the propagation routine PROP_DT also handles the spin propagation. The current algorithm used for spin propagation is: SimpleNumMagnetPrecession in pol-lib. and does not handle gravity.
GRAVITY: NO POLARISATION: YES
Example: Pol_Bfield_stop()
Parameters in boldface are required; the others are optional.
