  There are various versions of Bohm's theory. In the ‘minimal’ Bohm theory, formulated by Bell  (1982),[15]  the wave function is interpreted as a ‘guiding’ field (which has no source or any dependence on the particles) that deterministically governs the trajectories of the particles according to the so-called ‘guiding equation’ (which expresses the velocities of the particles in terms of the wave  function).[16]  The states of systems are separable (the state of any composite system is completely determined by the state of its subsystems), and they are completely specified by the particles’ positions. Spins, and any other properties which are not directly derived from positions, are not intrinsic properties of systems. Rather, they are relational properties that are determined by the systems’ positions and the guiding field. In particular, each of the particles in the EPR/B experiment has dispositions to ‘spin’ in various directions, and these dispositions are relational properties of the particles— they are (generally) determined by the guiding field and the positions of the particles relative to the measurement apparatuses and to each other.
