Dependent claims

A hybrid magnetic structure comprising:

a. a non-magnetic base;
b. a ferromagnetic pole;
c. at least two blocks of permanent magnet material;
wherein the at least two blocks of permanent magnet material are assembled onto said base on opposite sides of and adjacent to said ferromagnetic pole, in a periodic array, and have the magnetization orientations oriented in opposing directions and orthogonal to the height of said ferromagnetic pole, and wherein said blocks of permanent magnet material extend below the bottom edge of said ferromagnetic pole when assembled onto said base;
and,
wherein the ferromagnetic pole has a shaped tip which extends from a bottom edge to a shaped tip which extends beyond each block of permanent magnet material and wherein said shaped tip is shaped to produce a field gradient and to allow close proximity with a containment vessel.
