Rotating Magnetic Field Propulsion
Rotating and pulsed electromagnetic fields as a mechanism for generating lift and thrust — without combustion, without reaction mass, and without conventional aerodynamic surfaces.
The physics basis: when a time-varying magnetic field interacts with a ferromagnetic element, it exerts a body force (the Kelvin force) proportional to the gradient of the field energy density. When this field is produced by a rotating multi-phase coil assembly, the time-averaged force is directional. The question under investigation is whether the net force on the entire device can be nonzero — whether the internal forces between coils and the ferrite element can be converted into external thrust.
This approach connects directly to documented UAP research:
- The BUGA orb-sphere device — a European independently-built device documented over years of construction, operating on three-phase AC current, with a toroidal iron element and a spinning rotor at its core.
- Dr. Horace Drew's rotating magnets research — Caltech/Cambridge scientist analyzing crop circle physics as encoded UAP propulsion diagrams. His device: a central magnet counter-spinning against a four-magnet flywheel, driven by three-phase AC. Documented upward force during counter-rotation. See Rotating Magnets Propulsion.
- Ning Li's gravitomagnetic amplification — peer-reviewed work (Physical Review B, 1992) showing rotating ions in a superconductor lattice could produce gravitomagnetic effects orders of magnitude above bulk predictions. DOD-funded. Results classified.
- Podkletnov's rotating superconductor effect — reported 2% weight reduction above a rotating superconducting disc. Investigated by NASA Glenn and BAE Systems Project Greenglow.
- John Bedini's pulsed motor anomalies — decades of documented anomalous energy output from asymmetrically pulsed rotating magnetic field experiments.
Design Alternatives Under Investigation
Three alternatives have been investigated through simulation and analysis. Each is a distinct physics hypothesis. The results of each investigation are fully documented — physics derivations, simulation code, raw outputs, and conclusions.
1. Rotating Permanent Magnet Array — Kelvin Gradient Lift Drive
Status: Stalled. Sub-approach A eliminated. Sub-approach B pending ElmerFEM.
Rotating asymmetric magnet array generates upward Kelvin gradient force; directional problem identified.
A rotating asymmetric permanent magnet array positioned above a ferromagnetic target plate. The idea: the Kelvin body force on the plate should be upward (toward the magnets), and by Newton's third law the magnets (and craft) should be pushed upward with equal force — lift.
What the simulation showed: the Kelvin force is always attractive. The plate is pulled toward the magnets, yes — but the magnets are pulled toward the plate. Both parts of the device are pulled toward each other. For a craft above a steel ground plate, this means the craft is pulled downward.
The force magnitude was sufficient (7.54 N at 3.4 cm gap) but the direction is wrong for free-flight lift. Sub-approach B (eddy current repulsion via time-varying field — used in maglev trains) is pending simulation.

Status: Secondary. Thrust confirmed. Free-flight not viable. Near-surface hover viable below 5× device radius.
High-voltage asymmetric conductor generates electrostatic thrust confirmed in vacuum; requires external ground plane.
Based directly on the experimentally confirmed Buhler result (Dr. Charles Buhler, NASA Kennedy Center). The mechanism: electrostatic pressure P = ε₀E²/2 acts outward at every conductor surface. For an asymmetric conductor (hemisphere, cone), the field is concentrated at the apex and weaker at the base — the integral over the whole surface is nonzero, producing a net force toward the apex.
What the simulation showed: the Buhler force is real. 9.5 mN at 10 kV, scaling exactly as V². A 30-degree cone is 3.1× more efficient than a hemisphere. The critical finding: an isolated conductor (no ground plane) produces exactly zero net force — the force is an interaction between the conductor and the ground plane, not internal to the conductor. Free-flight requires a different mechanism.

Status: Active. Large internal Kelvin force confirmed. Spinning rotor mechanism under investigation (Day 5).
Three-phase rotating electromagnetic field drives toroid; 1.91 N internal Kelvin force at one amp.
Based on the BUGA orb-sphere device. Three electromagnetic coils arranged 120° apart, driven by three-phase AC current, produce a continuously rotating magnetic field above a soft iron toroid. The rotating field exerts a Kelvin body force on the toroid of 1.91 N at 1 amp — far exceeding the 0.5 kg lift threshold at 1.6 A.
What the simulation showed: the force is real and large (1,479× the initial analytical estimate — the coil is 1 cm above the toroid surface, not 3 cm as assumed; near-field scaling gives (3/1)⁴ = 81× more force). But the force is internal: the coil assembly experiences exactly −1.91 N as Newton's third law requires. Net external = 0. The spinning rotor is the remaining candidate for converting this large internal force into external thrust.
→ Full Investigation Record: Attempt 3The Core Barrier This Investigation Is Working Against
Every classical electromagnetic mechanism investigated so far produces forces that are either:
- Internal — equal and opposite forces act on different parts of the device; net external force is exactly zero
- Externally-grounded — the force is an interaction with an external reference (a ground plane); no ground plane, no force
This follows directly from Newton's third law. In a closed electromagnetic system, you cannot generate net linear momentum without expelling mass or radiation.
The reason this investigation continues: the question is whether there exists a mechanism that couples the device to an external reference without an obvious exhaust product. Three candidates exist in the literature:
- Gyroscopic coupling to Earth's gravitational field — a spinning rotor precessing in Earth's gravity transfers angular momentum to the Earth through the gravitational coupling. If the reaction geometry is asymmetric, a net vertical force on the craft might result.
- Gravitomagnetic coupling — at sufficiently high field rotation rates or with superconducting materials, the device might couple to the gravitomagnetic field of the Earth, producing a force analogous to magnetic induction but in the gravity sector.
- Electromagnetic radiation pressure — at microwave frequencies (3.4 GHz+), the EM momentum force becomes significant. A directional microwave emitter produces thrust proportional to power/c.
Day 5 investigates the gyroscopic coupling mechanism for the BUGA device rotor.
