text: But when magnetic field is applied then the symmetry may become broken because the magnetic moment of nucleon can precess in a magnetic field (if the spin of neutron is perpendicular to a magnetic field, the precession is physical), thus the virtual characteristic may become a physical one, which can be measured in experiment, see Ref.1.
