The Magnet

[4.133]

Let us now recall to ourselves the striped particles of the first element, which were quite accurately described earlier in the article 87 and following of Part 3.

Moreover, let us consider all that was said in Part 3, article 105 to 109, about star I, applying it here to the Earth.

Let us assume that there are many channels in its central region, parallel to its axis, through which the striped particles, coming from one pole, can freely go to the other.

These channels must be so excavated to their size that those receiving the striped particles from the Southern pole cannot receive any others coming from the Northern pole, and vice versa, those receiving Northern ones do not admit Southern ones.

This is because, just like coils, they are twisted in one direction or the other. Moreover, the same particles can only enter through one part of these channels, but cannot return through the opposite part due to the very thin extremities of the branches bent in spirals within these channels toward that part along which they usually progress.

Hence, after these striped particles have traversed through the entire Earth along straight or equivalently straight lines parallel to its axis, passing from one hemisphere to the other, they return through the surrounding ether to the same hemisphere through which they initially entered the Earth. Thus, they again permeate it, composing a kind of vortex there.

There are no suitable channels for receiving striped particles in air or water.

[4.134] The striped particles return from one pole to another from that ether.

4 different bodies could be generated:

  1. The inner crust of the Earth or the metallic part
  2. Water
  3. The outer earth
  4. Air

These are mentioned in Part 3, article 113.

No traces of channels suitable for receiving the striped particles have been left, except in the thicker particles of that ether.

All these thicker particles of ether initially converged towards the inner crust of the Earth. None of them could be present in water or air.

This is because:

  • there are no sufficiently thick particles there
  • being fluid bodies, their particles constantly change their position.

Therefore, if there were channels there once, corrupted by this continuous movement, they would have been destroyed by now.

[4.135] There are also no channels in any bodies of the outer earth except in iron.

The inner crust of the Earth consists of partly branched particles attached to each other and partly others that move through the branched intervals here and there.

Such channels cannot exist in these more mobile bodies due to the reason mentioned.

They can only exist in the branched ones. As for the outer earth, no channels were indeed present in it initially, as it was formed between water and air.

However, since various metals have ascended from the inner Earth to this outer one, although all those formed from the more mobile and solid particles should not have such channels, certainly that which consists of branched and thick but not so solid particles cannot be without them. And it is very reasonable to believe that iron is such.

Why such channels exist in iron.

[4.136] For no other metal is so difficult to be bent by the hammer, resists fire less, or can be rendered less fusible without the addition of another substance. These three characteristics indicate that its fragments are more branched or angular than those of other metals, and hence, they are more firmly connected to each other.

Nor does it matter that some of its masses easily melt upon the first exposure to fire; at that time, their fragments are not yet attached to each other, and therefore, they are easily agitated by the heat. Furthermore, although iron is harder and less fusible than other metals, it is also one of the least dense, and it easily corrodes with rust or is eroded by strong acids. All of which indicates that its particles are not denser than those of other metals, such as the thicker ones, but that many channels are contained in them.

How they exist even in each of its fragments.

[4.137] I do not want to affirm here that there are complete holes in each fragment of iron, like coiled structures, through which the striped particles pass.

Nor do I want to deny that many such holes may be found in them. It will suffice here to assume that halves of such holes are engraved on the surfaces of each of the fragments in such a way that, when these surfaces are properly joined, they form complete holes. And it can be easily believed that these thicker, branched, and perforated particles of the inner Earth, from which iron is made, were divided in such a way that half of these perforations remained on the surfaces of the fragments separated from them. These fragments were then pushed up through the veins of the outer earth, propelled by the spirit or acrid juice permeating them, gradually ascending into its cavities through exhalations and vapors.

How these channels are rendered suitable for admitting striped particles coming from either side.

[4.138] In this ascent, the alignment of these channels cannot always be the same. This is because they are angular and encounter various irregularities in the veins of the Earth.

When the striped particles, coming with force from the inner Earth, seek their paths throughout the outer Earth, they find these channels of fragments situated in such a way that, to continue their motion along straight lines, they attempt to enter through the same openings through which they used to exit.

However, they encounter these openings with very small extremities of the branches that protrude between the spirals of the channels, hindering the progress of the returning striped particles, as mentioned before.

Initially, these extremities resist the particles, but frequently, under repeated impact, they gradually bend in the opposite direction or even break.

Subsequently, when these channels, whose position within the fragments has changed, turn their other openings towards the striped particles, these extremities encounter them again, gradually bending them in the opposite direction.

The more frequently and longer this process is repeated, the easier it becomes for the extremities of these branches to undergo flexion in both directions.
