1. A system for extracting oxygen from a fluid, comprising:
four separator tubes arranged adjacent to one another to thereby form a central space between the four separator tubes, the four separator tubes defining four separate fluid flow paths;
a flow divider positioned inside a longitudinal portion of each separator tube of the four separator tubes proximate to a downstream end of each separator tube of the four separator tubes, wherein the flow divider includes an upstream end and a downstream end, and extends from the upstream end to the downstream end and radially spans each separator tube of the four separator tubes from a first lateral side of each separator tube of the four separator tubes to a second lateral side of each separator tube of the four separator tubes to thereby fluidically isolate a first side of the fluid flow path of each separator tube of the four separator tubes from a second side of the fluid flow path of each separator tube of the four separator tubes downstream of the upstream end of the flow divider; and
at least one magnet positioned around, and opposite the central space of, the four separator tubes proximate to the first side of the fluid flow path of each separator tube of the four separator tubes, the at least one magnet positioned upstream of the upstream end of the flow divider to establish a magnetic field asymmetrically inside and across the fluid flow path of each separator tube of the four separator tubes, wherein for each separator tube of the four separator tubes, a magnetic field gradient of the magnetic field has a magnitude that is greater on the first side of the fluid flow path as compared to the second side of the fluid flow path to concentrate oxygen as molecular O2 on the first side of the fluid flow path.
