NOVELTY - A magnetic carbon nanomaterial is produced by (a) heating an electrolyte media to obtain a molten electrolyte media; (b) positioning the molten electrolyte media between an anode and a cathode of an electrolytic cell; (c) introducing a magnetic additive component within the electrolytic cell; (d) introducing a source of carbon within the electrolytic cell; (e) applying an electrical current to the cathode and the anode in the electrolytic cell; and (f) collecting the magnetic carbon nanomaterial product from the cathode. USE - Production of magnetic carbon nanomaterial used in medical applications, biomedical applications, as a catalyst and for medical imaging, precise positioning, consumer electronics, information storage, for waste water treatment and electrochemical sensors and for carbon nanomaterial product (all claimed). ADVANTAGE - The greenhouse gas footprint of processes and systems that make a magnetic carbon nanomaterial product is decreased. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) system for producing a magnetic carbon nanomaterial product comprising (a) an electrolysis cell that comprises greater than or equal to 1 walls that define a plenum, (b) an anode and a cathode that are positioned within the plenum, where the plenum is configured to receive an electrolyte media between, and (c) a magnetic additive component where the electrolysis cell is further configured to receive an electrical current that is applicable to the anode and the cathode to initiate an electrolysis reaction for making the magnetic carbon nanomaterial product; and (2) electrolyte media for making a magnetic carbon nanomaterial product comprising (a) a carbonate; and (b) a magnetic additive component.
