1. A magnet for use in isolating macromolecules from a mixture in a vessel when the macromolecules adhere to paramagnetic beads to form a complex, wherein the magnet comprises:
a. a cylindrical wall defining a cylindrical opening, said cylindrical wall extending from a first end to a second end defining an axis; and
b. one or more discontinuous walls defined by one or more segments extending from at least a portion of the cylindrical wall along the axis and one or more gaps disposed between the one or more segments;
wherein a magnetic field is formed, when in use, within the vessel.
