An inductive motion sensor (MS) connectable to a subject (16), the motion sensor having a coil (4) and a magnet member (3) movable relative to the coil (4). The magnet member (3) has at least four magnetic poles, whereby the number of south poles (S) is equal to the number of north poles (N). The pole strength of the magnetic poles is dimensioned and the magnetic poles are located on the magnet member (3) such that the magnet member (3) is situated in a neutral equilibrium position in a uniform magnetic field with respect to the forces exerted on the magnetic poles by the magnetic field.
