None Magnetic field in TestEm3

Dear Users, I have problem with magnetic field in TestEm3. This example works with magn f. only in the case of particle beam. I changed mainly file in the aim of obtaining positrons emitted for betha source. Unfornately after this change I cannot to add magnetic field both in the file and also using command /testem/det/setFile 3 tesla Here I get information /testem/det/setFile 3 tesla not found This command works in this same example but for the beam. I have the system cosist with 1 layer which includes 3 absorbers. From the middle absorber positrons in all directions with differeds enegies are emitted. Help me please. I attached these two files Regards Pawel

#include "G4FieldManager.hh"
#include "G4TransportationManager.hh"

void DetectorConstruction::SetMagField(G4double fieldValue)
  //apply a global uniform magnetic field along Z axis

	G4FieldManager* fieldMgr
   = G4TransportationManager::GetTransportationManager()->GetFieldManager();

  if(magField) delete magField;		//delete the existing magn field

  if(fieldValue!=0.)			// create a new one if non nul
  { magField = new G4UniformMagField(G4ThreeVector(0.,0.,fieldValue));
  } else {
    magField = 0;
