Abstract:
A magnetic arrangement comprising:a first magnet to generate a first north-south magnetic field in a plane co-planer with a horizontal cross-sectional plane of a container; a second magnet to generate a second north-south magnetic field substantially opposing the first north-south magnetic field in a plane co-planer with the horizontal cross-sectional plane of a container; a third magnet to generate a third north-south magnetic field substantially perpendicular to the first and second north-south magnetic fields, directed radially away from the container, in a plane co-planar with the horizontal cross-sectional plane of the container; and a fourth magnet between the first and third magnet, to generate a fourth north-south magnetic field in a plane co-planar with the first north-south magnetic field, and directed away from the third magnet toward the first north-south magnetic field, the magnet arrangement to allow a fluid containing magnetic beads within the container to be poured from the container without a substantial loss of the magnetic beads.
