  virtual BVector Bfield (const Point3D&)const ;

  Get field.
  Return the time-independent part of the magnetic field in point P. This default action returns a zero field.

  virtual BVector Bfield (const Point3D&,double)const ;

  Get field.
  Return the magnetic field at time t in point P. This default action returns the static part BField(P).

  virtual EBVectors EBfield (const Point3D&)const ;

  Get field.
  Return the static part of the field pair (E,B) in point P. This default action returns EBVectors(EField(P), BField(P)).

  virtual EBVectors EBfield (const Point3D&,double)const ;

  Get field.
  Return the field pair (E,B) at time t in point P. This default action returns the static part EBfield(P).

  EMField () ;

  Default constructor.
  Construct zero field.

  virtual EVector Efield (const Point3D&)const ;

  Get field.
  Return the time-independent part of the electric field in point P. This default action returns a zero field.

  virtual EVector Efield (const Point3D&,double)const ;

  Get field.
  Return the electric field at time t in point P. This default action returns the static part EField(P).

  static const BVector ZeroBfield ;

  The constant representing a zero magnetic field.

  static const EBVectors ZeroEBfield ;

  The constant representing a zero electromagnetic field.

  static const EVector ZeroEfield ;

  The constant representing a zero electric field.

  virtual void scale (double) = 0 ;

  Scale the field.
  Multiply the field by scalar. This method must be defined for each derived class.
