The relationship between the magnetic field direction and the flopped ferroelectric polarization has been investigated for multiferroic MnWO 4. We have observed that the ferroelectric polarization flop direction is switched without applying an electric field, when the direction of an applied magnetic field slightly deviates from the b axis within the ab-plane. The polarization flop direction during the phase transition between P//a and P//b phase in a canted magnetic fields has been experimentally determined. The stability of magnetoelectric domain walls in a canted magnetic field would play a key role in the directional control of the electric polarization flop phenomenon.
