Abstract
The present invention relates to a device exploiting magneto-hydrodynamics (MHD) for localized delivery of material into a target or extraction of material from a target. The device includes a frame () comprising a space () for conductive fluid and the material, at least one pair of electrodes (A,B) facing each other, a source of electric current (), a magnet (), and an opening (). The electric current and the magnetic field are synchronized so that the material can be moved from the volume between the electrodes through the opening towards the target or from the target through the opening towards the volume. According to the invention the volume is ≤2000 mm, in proviso that mean distance between tips of the electrodes is ≤20 mm.
