wherein the shaft comprises a plurality of branches fluidly coupled to the third nozzle, and
wherein the plurality of branches and the third nozzle are arranged distal to the magnetic brake.
2 . The nozzle assembly of claim 1 , wherein the magnetic brake comprises:
a magnet disposed on a protrusion of the rear portion; and
a conductor disposed within an aperture formed in at least one of the stator and the rotor.
3 . The nozzle assembly of claim 2 , wherein the conductor comprises a non-ferrous metal.
4 . The nozzle assembly of claim 2 , further comprising a magnetic shield disposed outward from the longitudinal axis relative to the magnet.
5 . The nozzle assembly of claim 4 , wherein the magnetic shield comprises a ferrous metal.
6 . The nozzle assembly of claim 2 , wherein the magnet comprises a cylindrical shell.
7 . The nozzle assembly of claim 6 , wherein the cylindrical shell includes a plurality of radially polarized portions.
8 . The nozzle assembly of claim 6 , wherein:
a first radially polarized portion of the plurality of radially polarized portions includes a first pole having a first magnetic polarity and a second pole having a second magnetic polarity opposite the first magnetic polarity, wherein the first pole is disposed closer to the longitudinal axis than the second pole; and
a second radially polarized portion of the plurality of radially polarized portions includes a third pole having the first magnetic polarity and a fourth pole having the second magnetic polarity, wherein the fourth pole is disposed closer to the longitudinal axis than the third pole.
9 . The nozzle assembly of claim 8 , wherein the first radially polarized portion and the second radially polarized portion are adjacent to one another in the magnet.
