    "inventor_name": "Andrew A. Melnichenko",
    "publication_year": 1996,
    "device_name": "Ferromagnetic Resonance Generator",
    "goal": "Generate electrical power (free energy) using magnetic resonance and partial separation of magnetic fields.",
    "problem_addressed": "Provide a low-cost, self-charging power source without relying on conventional energy inputs.",
    "concept_summary": "A primary low-voltage battery drives a resonant circuit that magnetizes a ferromagnetic core. The core's magnetic field is deliberately only partially coupled to the magnetization coil, leaving a large portion of magnetic energy unlinked. During demagnetization, a detachable secondary winding extracts this otherwise unused magnetic energy as electricity, allegedly producing more output power than the input.",
    "detailed_description": "The invention uses a magnetization coil placed at a distance from a ferromagnetic core (e.g., ferrite or steel) so that only a fraction of the core's magnetic flux links the coil. The primary coil is energized by a small DC source (e.g., a 1.5 V battery) which creates an alternating voltage through resonance. When the primary current is switched off, the core's magnetic elastic energy is released. A secondary winding, isolated during magnetization by diodes or a rectifier, conducts only during the current-fall (demagnetization) phase, converting the released magnetic energy into usable electric power. The topology may include multiple cores, laminated sheets, or dumbbell-shaped cores to shape the magnetic field and minimize inductive coupling. The system can be powered by any pulsating voltage source and may employ various pulse-conversion schemes (booster, chopper, inverter).",
