The invention relates to a dynamic method for the wet separation of a liquid-phase suspension, which consists of microparticles comprising a magnetic material, and a liquid medium in which said particles are in suspension. The inventive method comprises the following steps: a) the suspension is confined in an enclosure (1) having at least two pre-determined dimensions, e.g. length and depth; b) at least a plurality of basic magnetic fields (2n,p) are used which are distributed along a Halbach semi-configuration, the respective ends thereof located opposite the enclosure (1) generating a vector sum of said basic magnetic fields corresponding to a capture magnetic field that passes through said enclosure (1) and exerting a magnetic attraction on the microparticles, while the respective opposite ends thereof generate no magnetic field; c) said capture magnetic field (13) is generated and used to capture a microparticle-enriched solid phase in said enclosure (1) and a microparticle-depleted liquid phase is subsequently drawn off from said solid phase.
