    "device_name": "Electromagnetic Motor",
    "goal": "Convert electrical energy into mechanical rotation (and potentially generate electricity) with high efficiency to address the energy crisis.",
    "problem_addressed": "Reliance on conventional energy sources and the need for more efficient power generation.",
    "concept_summary": "A reciprocating magnetic motor in which a permanent-magnet piston moves inside a cylinder between two electromagnetic assemblies. Polarity of the electromagnets is periodically reversed and field strength varied to pull and push the piston, producing continuous rotary output. The design incorporates sector-shaped permanent magnets, bar magnets, and magnetic spheroids in a damping fluid to reduce hysteresis and flux leakage.",
    "detailed_description": "The motor consists of an aluminum cylinder housing a stainless-steel piston that carries an elongated permanent magnet. At each end of the cylinder an electromagnetic assembly with copper windings, sector-shaped permanent magnets, and axially spaced bar magnets creates a controllable magnetic field. A distributor and rheostat network, synchronized with the piston motion, reverses polarity and adjusts current magnitude, causing the piston to reciprocate. Magnetic spheroids suspended in a damping fluid within a cavity reduce hysteresis losses. The reciprocating motion is converted to rotary output via a crank and shaft, which can drive a pulley, generator, or other load. The system is powered initially by a 12-V battery and is claimed to become self-sustaining once running.",
