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.

2. Asymmetric Electrostatic Pressure Drive — Buhler Thrust

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.

3. BUGA Three-Phase Rotating Field — Rotating EM Field Drive

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.

The 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.
