If, in a given Lorentz frame, a closed circuit of conductors is stationary************************************************************************
and there is no Q or partial dB/dt source producing an E field acting on the
conductors' carriers, there can be no induced current in the circuit. The
"cutting of magnetic field lines" or the "change in enclosed magnetic flux"
or "the motion of a conductor relative to magnetic field lines" can be
confused and not always useful criteria for the existence (or not) of an
induced current in a circuit.
