Question Non-uniform fields 

Forum: Fields: Magnetic and Otherwise
Date: 25 Jan, 2010
From: Jonathan <Jonathan>

I'm new to Geant4. I've got a question about non-uniform fields. I need to add the magnetic field of a solenoid that to the detector geometry of an experimental set-up. I initially thought that it would be required to create a logical volume of the actual coil of the the solenoid. I want the field to be detectable throughout the detector because I want to include effects of the fringe field. If creating a logical volume of the solenoid coil is not required, how is the field determined within the detector itself? Surely the size, orientation and position of the solenoid coil is needed to determine the field within the geometry? The code for the magnetic field itself is already done as well as the code for the numerical procedures and step size. All that's needed is to incorporate the magnetic field into detector geometry. I've worked through a tutorial example which includes an example of how to add magnetic fields but I'm still unclear as to how such non-uniform fields are determined within the detector itself. I would appreciate it if someone could explain how this works or at least point to some example code that explains it better. Thanks.
