|
|
// Class description:
|
|
//
|
|
// Defines a tool to trace and visualise magnetic field lines
|
|
// To use this tool in a Geant4 application the user should
|
|
// create an instance of this class in the code as a run action.
|
|
// It will only work if a G4MagneticField field object is declared.
