    "inventor_name": "Felix Ehrenhaft",
    "publication_year": 1944,
    "device_name": "Magnetic Current Apparatus",
    "goal": "Demonstrate the existence of a magnetic current (flow of magnetic monopole-like particles) and magnetic-induced water decomposition, proposing a new form of energy transmission parallel to electric current.",
    "problem_addressed": "Absence of experimentally verified magnetic monopoles and a lack of alternative current carriers beyond electric charge.",
    "concept_summary": "Ehrenhaft reported that a strong magnetic field, applied to a U-shaped tube containing acidulated water and iron pole pieces, produces measurable oxygen alongside hydrogen, suggesting water decomposition driven by magnetism. He further observed bubbles and metal particles moving in characteristic patterns (cling, reverse buoyancy, whirligig rotation) when the magnetic field is switched on, interpreting these as evidence of magnetic ions (monopoles) and a magnetic current analogous to electric current.",
