Power From Magnetism

Power From Magnetism is the first of Harold Aspden's Energy Science Reports, dated 1994. It is a short technical briefing rather than a peer-reviewed paper, and it presents itself that way. Its stated audience is the people who evaluate invention rights — patent specialists and technical advisors — rather than academic referees. Aspden's opening argument is that patent practice is better suited than peer review to judging a "new science" invention at the drawing-board stage, because patent specialists approach an inventor's claim without the bias of established theory and then judge it on novelty and practical merit. That framing shapes how the report should be read: it is a case for a claim, addressed to people whose professional job is to assess claims.

This guide covers the arguments and numbers the available excerpts actually supply. The report's contents list names several sections — The Power Converter, Ferromagnetism, Magnetic Leakage Flux and the Adams Motor, The Solid-State Energy Probe Experiment — that are not represented in the material summarized here, and they are therefore not described. The thermoelectric section and the thermodynamics appendix are the least completely represented, so the account of them below is correspondingly partial.

The central claim

Aspden's thesis is that magnetic inductance conceals an energy source. He calls that source the aether, and treats it as an active medium rather than a passive void. In his account, when a primary magnetic field acts on the free conduction electrons in a metal, there is inevitably a half-field reaction — the A-field — opposed to the primary field. This A-field reaction in the vacuum or aether is, he says, the basis on which inductive energy is stored as a magnetic field. From that starting point he argues that a ferromagnetic core can act as a catalyst giving access to vacuum energy, and that devices built on this principle can operate "over-unity."

The report is therefore not a claim about a single machine. It is a claim about the physics of inductance, with several proposed routes to exploiting it. The aether framing connects to Aspden's wider aether-cosmology-claim.

Defining "over-unity"

Aspden is careful about the term, and the care is worth preserving. For a device to operate over-unity, he writes, its power input (usually electrical) must be exceeded by the power output, whether that output is electrical, mechanical or thermal.

He then separates this from the heat pump. A heat pump might move 10 joules of room heat using 1 joule of electrical energy, but Aspden insists this is not 11-to-1 over-unity performance: the true input then is 11 joules and the output is also 11 joules. The relevant figure of merit for a heat pump is the coefficient of performance, governed by the reverse Carnot factor. Aspden's definition is narrower and more demanding: over-unity means the output of more useful energy than is supplied as useful energy input. On his account, 11 joules of heat output are not as useful as 1 joule of electrical input, so the heat pump does not qualify. A device would qualify if it produced excess electrical output, or excess heat at a temperature so elevated relative to input heat that the Carnot criteria are surpassed.

This distinction is the report's working definition, and it is the standard against which its later experiments should be judged.

The air-gap asymmetry experiment

The experimental core of the report concerns a magnetic circuit with two coils, A and B, and an air gap. Aspden's setup: establish a given magnetic flux across the air gap with coil A as primary and no current in an identical coil B, and note the current required. Then reverse the roles, using coil B as primary to establish the same flux in the same direction, and note the current required. He reports that less current is needed in B than was originally needed in A.

Translated into inductance energy storage, this means coil A requires more inductance energy input than coil B to achieve the same magnetic condition in the gap. Aspden's explanation is that in both conditions there is a current flow in the aether at the air gap, virtually equal and opposite to that in coil B. The aether reaction current and coil B's current complement each other, so very little discrepancy between them is needed to establish the magnetic polarization in the iron core, and virtually all the energy supplied to coil B is stored in the air gap. With coil A excitation and no power on coil B, more energy is demanded because the air-gap energy state is supplemented by flux leakage.

He then asks how energy gets from coil A to the gap at all, given how little action is needed to create or suppress magnetic polarization in the iron. His answer invokes domain flux rotation: the coil A current urges flux rotation in domains whose host crystals do not have easy axes of magnetization aligned with the coil axis. Once that scenario develops, he writes, we are entering the realm of "free energy."

The "Mystery Energy Source" energy balance

The report's energy-balance experiment is described with specific numbers. As the magnetic circuit is made to require more magnetomotive force, the input energy rises while the gap-stored energy rises faster. With N = 9, Aspden reports the primary input increased to 100 V with a primary current of 538 mA, while the component supplying the pole-gap region remained at 47.1 V. His summary: the input power feeding the pole gaps has doubled but the energy stored in the gap has trebled.

He reads the downward curve of his Fig. 5 as showing that as the magnetic circuit demands more MMF, the ferromagnetism of the core becomes subject to more domain flux rotation and sheds energy, making it available as a form of inductance energy that can be tapped mechanically by closing the pole gaps.

The account was submitted to Physics Education under the title "Mystery Energy Source." Aspden quotes its closing passage, in which he calls the ferromagnet a catalyst giving access to a new and plentiful source of energy tapping into the vacuum energy source that determines the Planck action quantum, and challenges readers to repeat the experiment and reconcile the result with what is taught about energy conservation.

Moullin's Fig. 113 as offered corroboration

For readers who prefer to rely on published work, Aspden points to Fig. 113 at p. 173 of E. B. Moullin's Principles of Electromagnetism (3rd ed., Clarendon Press, 1959). He reports that for a 7 mm gap in a rectangular core four times larger in linear scale than his own — corresponding to his 7 card thicknesses — Moullin's data show the reluctance gap energy to be twice that supplied as inductance energy.

Aspden immediately qualifies this. Moullin kept the applied voltage constant and did not use a separate search coil, and in discussing leakage flux effects missed the full significance of his experiment. Aspden says he only became a discerning reader of the book after nearly 30 years of owning it, when he heard of "crank" claims about switched reluctance motors delivering more power out than in. This is a reinterpretation of another researcher's data, not an independent confirmation of Aspden's own experiment, and the report presents it as such.

The thermoelectric route

A separate section proposes converting heat to electricity without a Carnot limitation. The mechanism is a transverse magneto-thermoelectric effect. In the general case, a temperature gradient along one axis (x) and a magnetic d.c. field acting transversely (y) set up an electric potential in the mutually orthogonal direction (z); the magnetic field deflects ions according to charge polarity, diverting heat as kinetic energy into a voltage. Aspden presents magnetohydrodynamics as the well-known power-generating technology of this type.

Aspden's solid-state implementation uses a steel lamination: a temperature differential in the plane of the lamination (x), magnetization in the other planar direction (y), and a resulting potential between the lamination's opposite surfaces (z). The intrinsic magnetic polarization of the domains in the steel or nickel removes the need for externally powered magnetizing windings. When current flows in the z direction through an external circuit, the lamination cools as the generated EMF delivers power — a very efficient technique of refrigeration using a solid-state technology, conditional on assuring heat flow in the metal and a transverse current flow that does not itself lose heat.

The prototype work used a magnetic core of bimetallic laminations, steel film plated with a layer of nickel on one surface. The intended principle is to induce magnetization loss in the laminations, producing heat that is conducted away within the laminations; circulating eddy currents near the lamination edges provide z-axis flow, and the intrinsic domain magnetism acts on the x-axis heat flow carried by electrons. Aspden hopes these combine to set up a forward EMF augmenting the current flow — in effect a negative resistance making the device regenerative, so that heat input produces electrical power. He states that the breakthrough resides in the fact that the experiment does show the regenerative action, and that the process would be over-unity because waste heat at ambient temperature could be converted into useful electricity, resulting in overall cooling.

The B–H loop diagnostic

The thermoelectric work is monitored with a transformer core wound with a primary and a sensing secondary, with a series resistor feeding the oscilloscope X plates (proportional to H) and a 2 µF capacitor in series with a 100,000 ohm resistor feeding the Y plates (a time integral of the rate of change of flux density B). At low current, below saturation and at mains frequency, Aspden reports the B–H trace as a straight line angled to represent the magnetic permeability — a line meaning negligible loss. He notes that a B–H loop with little eddy current has a special hysteresis shape, whereas an over-dominant eddy-current effect makes the loop elliptical, with the loop width measuring the loss portion of the reactive volt-amp input. He then reports that on bringing the current up to near mid-range, the B–H loop became very wide and quite elliptical.

The First Law of Thermodynamics appendix

Appendix A argues that the First Law of Thermodynamics does not hold in one specific case: when a ferromagnetic substance cools through its Curie temperature, it releases heat over and above that associated with its normal specific heat. Aspden says this extra heat equals the sum of the magnetic energy established (the energy needed to set up the same field conditions in an air-cored solenoid as exist in the saturation state of the magnetism in each domain) plus the work done in setting up the associated mechanical strains. Since the only system recognized as present is the ferromagnet itself, he argues there is no way to keep an energy balance under the First Law unless there really are two systems inside one another, one supplying energy from a source not sensed in temperature terms.

The appendix also takes issue with textbook wording, objecting that "heat" is a scalar form of energy whereas a temperature difference has direction and is a vector, and that "heat flow" is the term that can properly be said to have the prescribed definition. Aspden's broader point is that thermodynamics has historically been used to draw an arbitrary line between the possible and the impossible, a line he says is not holding steady. This argument relates to the wider laws-of-nature-critique, though Aspden's route to it is physical rather than biological.

There is a tension inside the report here. Aspden argues the First Law does not hold for the Curie-temperature case, yet elsewhere he describes his comments on perpetual motion and energy conservation as needing an aether to avoid breach of the First Law of Thermodynamics. The two framings — the law fails, and the aether is needed to avoid breaching the law — sit uneasily together, and the report does not reconcile them.

The A-field derivation and the g-factor

Appendix B derives the A-field reaction. Aspden writes the field relation as B = gB − A (equation 6), combines it with earlier equations to get δE = (gB − A)(A)/4πg (equation 7), differentiates with respect to A to find the maximum at gB − 2A = 0 (equation 8), and concludes that the A-field reaction is exactly half of gB, so that g is precisely 2, giving δE = B²/8π (equation 9) — the conventional magnetic field energy density formula.

His empirical anchor is the gyromagnetic ratio. He notes that the measured ratio of electrical current moment to angular momentum is twice that expected from conventional theory based on the electron's known charge/mass ratio, and identifies this factor of two with the g-factor he derived. He calls the interpretation of the gyromagnetic reaction in terms of the A-field indisputably strong, but adds that it requires recognizing an A-field vacuum reaction involving the charges that account for Maxwell displacement currents.

This is the report's strongest claimed empirical agreement. It is also a derivation by Aspden matched against a known measured value, with the match interpreted through his own framework — not an independent test of the A-field hypothesis.

Limits of the evidence

Three limits are visible in the material itself.

First, the experiments are Aspden's own, reported with specific numbers but not independently replicated within the source. The air-gap asymmetry and the N = 9 energy-balance result are reported results, not measurements reproduced by others.

Second, the "Mystery Energy Source" letter was rejected by Physics Education peer review. Aspden quotes the referee's objection: that he presents his results as evidence of a fundamental flaw in accepted theories, that those theories have proved so widely and exactly verifiable that something more than a few simple tests is needed to shake one's faith, and that careful measurements of current and voltage, observations of phase angles, and simple controls such as removing the yoke altogether or increasing the number of cards would be required. The source supplies this counter-evidence against its own central experimental claim, and it should be read alongside the claim.

Third, the corroboration offered is interpretive. Moullin's Fig. 113 is another researcher's data, read by Aspden as supporting his conclusion, with Aspden himself noting that Moullin kept voltage constant, used no separate search coil, and missed the significance. The Nexus editorial claim of "hundreds and hundreds" of duplications of the Adams device is a magazine assertion, not a measurement, and Aspden himself flags a troublesome question about Adams over-unity efficiency claims. These third-party assertions should not be treated as established.

The report's over-unity framing connects to reported-vs-measured-performance, the distinction between a reported figure and an independently measured one. Its argument that patent specialists are better judges than peer reviewers engages patent-application-as-evidence directly. Its energy-extraction theme is distinct from, but comparable to, the earth-field-energy-extraction-claim advanced by a different inventor.
