Eric Laithwaite: Inward Travelling Magnetic Field

Eric Laithwaite was a smiling subversive who became a mainstream outcast.

Eric Laithwaite became a hated heretic because [amongst other things] he didn’t succumb to the Settled Science mantra:

Thou shalt solely solve simultaneous equations.

5.5 Levitation with a degree of freedom

Another experimenter in levitation, E. C. Okress (Okress et al ., 1952), and myself both found it possible (independently) to levitate a metallic object with a single coil.

The apparent impossibility of such a feat, for myself at least, was broken only when I realised another great bedrock on which electromagnetic theory can be erected, and I have frequently declared it to students in the following manner:

‘In any problem concerned with electromagnetic induction, the flux pattern cannot be determined until the secondary current distribution is known, yet until the flux pattern is known, the secondary current pattern is unknown’.

Such a statement is not to be interpreted as saying that induction processes cannot be evaluated.

It states, however, that human failing which demands, among other things, that we shall always have simultaneous equations to solve is the result perhaps only of our lengthy process of ‘explaining’ electromagnetism in terms of classical physics.

As in life, if you tell one lie, you usually have to tell another to cover it up!

The mainstream is still disturbed by Eric Laithwaite’s smile because it can’t determine whether he enjoyed 1) science or 2) trolling or 3) both at the same time.

A wonderful example is the Inward Travelling Magnetic Field.

Permanent magnets are difficult things to understand.
In fact, if we’re absolutely honest with ourselves we don’t understand them.

If we could only produce inward travelling fields

The lesson to be learned from the statement on purely physical considerations, however, is that the apparent lack of ‘ingredients’ required to produce a desired effect on an object will often be solved by the existence of the object itself, often giving therefore apparently impossible achievements.

For example, the primary coils of a single-phase induction motor are apparently incapable of producing any kind of rotating field, ‘and therefore’, doubtless cried the pessimists of 1880 ‘it can never run’.

There is a piece of prose by Minnie Louise Haskins, made more famous by its quotation by King George VI in speaking to his people at Christmas 1939 when all seemed uncertain in World War II, that could well still be used to put heart into those who fear the limitations of electromagnetism:

‘And I said to the man who stood at the gate of the year:
“Give me a light that I may tread safely into the unknown”
and he replied:
“Go out into the darkness and put your hand into the hand of God. That shall be to you better than light and safer than a known way.” ’

So might a prophet of 1880 have said to Tesla:

‘Ask not how the rotating field shall be produced.
Only place a rotor in the path of the pulsating flux and give it a push.’

Levitation by induction was achieved, I am convinced, by just such acts of faith, for permanent magnets came before electromagnets and Earnshaw’s theorem came up like barbed wire each time stable levitation was considered.

For me, stability was achieved initially only through the mechanism of setting up inward-travelling fields by feeding inner and outer coils of the levitator shown in figure 5.4 with currents of appropriate phase difference.

Laithwaite produced a model of the Earth that’s far superior to the Dantesque Nine Concentric Circles of Torment promoted by the mystics of Earth Science.


The 21st century Earth Scientists have a problem with their medieval mysticism that defines Nine Concentric Circles of Hell within the Earth.


Laithwaite’s model echoed Edmond Halley’s work that suggested the Earth’s magnetic field has two surface poles and two inner sphere poles at a depth of about 800 km.

Sir Edmond Halley also recognised the Earth’s magnetic field was quadrupolar.

The Norwegian Christopher Hansteen also concluded [in his treatise that was finally published in 1819] that “one magnet was insufficient to describe the Earth’s field, two being required, giving four magnetic poles in all, the two new poles being located north of Siberia and in the south-easterly Pacific.”



As data accumulated, Halley noticed how the line of zero declination drifted westward.

Apparently the whole pattern of Earth’s magnetism was creeping toward the west at a pace that would complete a circuit in a couple thousand years.

To explain this curiosity, Halley proposed that the Earth has two north and two south magnetic poles. Two of these poles lay on the surface, the other two lay on an inner sphere about 800 km deep.

By cleverly adjusting the slow westerly rotation of this inner sphere, he could reproduce the observed variations to some extent.

Earthquakes occurring at a depth of less than 70 km (43 mi) are classified as “shallow-focus” earthquakes, while those with a focal-depth between 70 and 300 km (43 and 186 mi) are commonly termed “mid-focus” or “intermediate-depth” earthquakes.

In subduction zones, where older and colder oceanic crust descends beneath another tectonic plate, deep-focus earthquakes may occur at much greater depths (ranging from 300 to 700 km (190 to 430 mi)).

Eric Laithwaite’s inward travelling magnetic field provides another variable facet of a system that drives [what can best be described as] Magnetohydrodynamic Gravity.


Independent observers might consider the Lorentz Force is best illustrated by the dynamic helical motion of the Milky Way as it hurtles through space.

A system that’s been spun up by the Lorentz Force creates a Dynamic Vortex Pressure [aka Gravity] that sorts [aka sequences] the embedded objects by density.





Stephen Hurrell is a truly remarkable scientist whose application of the scientific method has enabled him to unravel many of the mysteries that surround the history of the Earth.
