The Ferrite Sleeve Inductor.

[GSM]

This extremely high 'Q' inductor was imagineered 18 months ago according to rules of core electron orbit alignment due to alternating charge flow within a coil winding, as opposed to the 'magnetic field' of a coil inducing a 'magnetic field' within the core of a coil.

This inductor (or a toroidal version of it) was intended for use in 'energy' related projects, but I realised that proof of concept could first be tested by trying it as if a 'Loop Antenna'; whereupon it worked exactly as expected, with notably excellent reception from 100kHz to 10MHz. It was capable of rendering perfectly listenable distant and otherwise inaudible signals on AM portables, and would be good with cheap or solar powered radios in Africa, Australia etc.

Hence the compact Ferrite Sleeve Loop Antenna (FS Loop) became established as a working design.

Note -
1) It is the electrons within the wire of a loop inductor which transduce EM radiation - not its core; a ferrite core merely becomes part of the resonance of energy between coil charge flow induced core electron spin alignment deflections and tuning capacitor voltage development.
2) Coils transduce/ receive a photonic quanta stream; not radio 'waves'.
There are no waves, and most certainly there are not any 'magnetic wave components' to distant EM radiation !

For over a century we have been 'educated' to think of EM radiation as if being 'transverse waves', whereupon we are subsequently obliged to pass exams which ensure this has become our foundational knowledge base. Yet this merely compartmentalises our understanding, and ensures our inability to comprehend beyond. Also, no matter if this box would be made of metal, it will not, because it cannot, screen us from the effects of otherwise inexplicable longitudinal radiation (also not waves).

There is far too much argument about 'waves' propagating through an 'aether' - neither of which exist other than - in the minds of those who have not yet challenged the *unproven* beliefs used to establish their 'knowledge' !

Hi gsm, thanks for sharing your thoughts, sounds good to me.
Yes and they also built most of the human living systems (societies) and these also have little relation to reality (nature).

Thanks for your comment Tyson.

This was a SW FS Loop antenna for 1.7 to 6.2MHz.
The cardboard former is from inside a roll of parcel tape.
Rods are 100mm x 10mm dia standard MW/LW AM types.
Parcel foam insulation (essential) is about 1/4" or 5 to 6mm thick.
The tuning range is dependent upon your variable capacitor.
The 24x 0.2 wire is string or strimmer line spaced. Use 16x 0.2 for MW.
Gary used Litz wire, but not essential if turns spaced.
Aim to space winding turns out over 70 to 80% of rod length.

Overall about 4" long and 4" dia, but like having an outdoor wire with ATU !

Note - still directional at 6.2MHz so can null stations, interference or TVs and switch mode PSUs etc.

To connect to a SW portable merely connect one end of the coil with a croc lead to the collapsed whip antenna.
The coil couples resonantly with respect to its own self impedance reactance in surrounding free space !

Cheers ....... Graham.
Yes, peace love light, sadly not enough in our world at the moment.

Nice video.

Question....How does moving the ferrite to the perimeter of the dipole over the center take advantage of electron orbit alignment, rather than magnetic field? (I could see someone making an argument for these being the exact same thing). Have you tried building another coil with same amount of ferrite within the core, and testing relative Q factor?

Hi Armagdn03.

In answer to your question - yes - about 50 years ago - but it was 2010 before I realised the significance of my observations.

Q. Why have we never seen thick and/or long ferrite rod AM antennas ?
A. Because they do not work !

Charge flow within an energised winding precesses ferrite electron orbits close to the wire only.

Make the core too thick and it is then the ferrite electron orbits close to the coil which energise those more centrally located - NOT the coil !

This leads to electron orbit phase shift through a solid ferrite cross-section, with the central section becoming so far phase shifted wrt the ferrite electron orbits close to the coil, that losses limit the resonant 'Q' and thus *effective* permeability, irrespective of the manufacturer's stated permeability for the ferrite.

In a thick rod there is an axial region of central loss which becomes a conical interference vortex beyond both ends of the coil, and this loss effect increases with increasing frequency.

If I may question your use of the term dipole, because the electron spin field alignments within ferrite are progressive (like an amplitude wave) and not of one polarity or another as is so often simplistically and erroneously illustrated, including by Wikipedia.

When I think about electron spin alignments, whether within the free electron fluid within the wire of a coil, or whether within some core energised by adjacent electron alignment within the wire of a coil, this is so different from imagining the 'magnetic' H and B fields we are taught to think about, and calculate !

Hello again!

I concede to what you are saying about incorrect use of the term dipole as this is just a slice in time rather than a progression.

Where I have a problem in understanding is that the magnetic moment of an electron is caused (chicken or egg scenario) by its spin (this can be either orbital or axial). How can you have aligned spin and aligned magnetic moment share separate worlds?

Hi Armagdn03.

Of course your chicken-egg analogy is good, for you cannot have one without the other and neither came first, as indeed neither can there be any first with charge movement and magnetism, for they are simultaneous observations of a single electromagnetic occurrence.

I now wonder at your question of 'separate worlds', for there must be differences of understanding, which whilst being different might not necessarily represent an incorrect viewpoint relating to some specific but unstated working scenario.

Every orbiting electron constantly generates an 'axial' magnetic dipole, but unless its 'orbit' has been atomically aligned (as within magnetic material) they do not generate what we regard to be a physically measurable magnetic moment - unless - their spin orbits become mutually (magnetically) aligned by external charge motion, with this via a magnet or electromagnetically energised coil, both being bodies of aligned electron orbit spin field which cause adjacent electron orbits to similarly align axially.

Think of the fundamental force of attraction between two charge carrying conductors, it is no different with spinning electrons (magnetostriction). Magnets attract as their already aligned electron orbits seek to axially align with like rotating orbits. Learning about N and S poles and 'lines' of force between same might be illustrative, but it is not an explanation, and not properly educative.

This is why a gap or suitable insulation is essential both between adjacent turns of solid wire on high Q HF inductors, also between any resulting inductor and its core. The induced spin field alignment within an inductor is only temporary, and must maximally activate only those electron orbits free to become aligned - near the surface of the wire and core - without being damped by orbits more firmly atomically aligned or remanently coupled within the molecular lattices of either.

Often mentioned as being the 'skin effect' around a conductor, the same fundamentals apply to cores within inductive overwinds, though I had never read of this before I had the ferrite sleeve inductor constructed, and I have yet to see any mention of possibilities for a ferrite sleeve type of toroidal core.

Could a child's toy plastic or wooden ring spirally overwound with fine iron wire (Rodin coil type wind) make an ultra efficient HF impulse toroidal core which will not electromagnetically radiate precious energy to its surroundings ?
