A magnetic circuit consisting of two horseshoe magnet assemblies are placed opposite each other with water in between them. Each horseshoe magnet is one simple steel bar core and two block magnets attached at each end of the steel bar and facing outwards in the same direction - one magnet is North-out, the other is South-out. The two horseshoe magnets face each other to form a single magnetic circuit which flows through, in series, magnet-water-magnet-steel-magnet-water-magnet-steel-(magnet). How do the Bloch walls form in the water and in the steel? Is it possible to bias the Bloch walls in the water towards one side of the gap?
