Encyclopaedia Britannica, 11th Edition, Volume 4, Slice 1 "Bisharin" to "Bohea" The diamagnetic quality of this metal can be detected by means of a good permanent magnet, and its repulsion by a magnetic pole had been more than once recognized before the date of Faraday's experiments.

Second Sight A study of Natural and Induced Clairvoyance From the experiments of Faraday it appears that all matter is subject to the magnetic force as universally as it is to the gravitating force, arranging itself into three divisions, the ferromagnetic, paramagnetic, and diamagnetic.

The World's Greatest Books — Volume 15 — Science It was finally proved to be so; and the most complicated cases of magne-crystallic action were immediately shown to be simple mechanical consequences of the principle of diamagnetic polarity. Fragments of science, V. 1-2 From the molecular orbital diagram of N2, predict its bond order and whether it is diamagnetic or paramagnetic. Chemistry 2019-02-14T00:00:00Z All are diatomic, diamagnetic and positive; the corresponding group consists of sulphur, selenium and tellurium, also all diatomic and diamagnetic, but negative. Occult Chemistry Clairvoyant Observations on the Chemical Elements The more feebly magnetic bodies are classed as paramagnetics, and those which behave as described above are called diamagnetic substances. The New Gresham Encyclopedia Volume 4, Part 1: Deposition to Eberswalde 2011-04-14T02:00:57.977Z By a similar arrangement the feeble attractions and repulsions of the diamagnetic force have been made manifest. Six Lectures on Light Delivered In The United States In 1872-1873 Hence the deflection produced by these metals is due to their diamagnetic, and not to their conductive capacity. Fragments of science, V. 1-2 Can a molecule with an odd number of electrons ever be diamagnetic? Chemistry 2019-02-14T00:00:00Z The corresponding group contains phosphorus, arsenic and antimony: bismuth also belongs to it, but was not examined; they are triatomic, diamagnetic and negative. Occult Chemistry Clairvoyant Observations on the Chemical Elements He regarded the first class of substances as attracted, and the second class as repelled, and called them respectively paramagnetic and diamagnetic substances. Beacon Lights of History, Volume 14 The New Era; A Supplementary Volume, by Recent Writers, as Set Forth in the Preface and Table of Contents The former he called paramagnetic and the latter diamagnetic bodies. The Story of Electricity To account for diamagnetic phenomena this theory seems to fail altogether; according to it, indeed, the oft-used phrase, "a north pole exciting a north pole, and a south pole a south pole," involves a contradiction. Fragments of science, V. 1-2 Explain why is diamagnetic, while which has the same number of valence electrons, is paramagnetic. Chemistry 2019-02-14T00:00:00Z The first group is paramagnetic and positive; the corresponding one is diamagnetic and negative. Occult Chemistry Clairvoyant Observations on the Chemical Elements At first Faraday attributed the repulsion of diamagnetic substances to a polarity, separate and distinct from ordinary magnetic polarity, for which he proposed the name, diamagnetic polarity. Beacon Lights of History, Volume 14 The New Era; A Supplementary Volume, by Recent Writers, as Set Forth in the Preface and Table of Contents That the force which does so is therefore 'distinct in its character and effects from the magnetic and diamagnetic forms of force. Faraday as a Discoverer This metal is a better conductor of electricity, but less strongly diamagnetic than bismuth. Fragments of science, V. 1-2 Materials with unpaired electrons are paramagnetic and attracted to a magnetic field, while those with all-paired electrons are diamagnetic and repelled by a magnetic field. Chemistry 2019-02-14T00:00:00Z That the deportment of magnetic crystals is exactly antithetical to that of diamagnetic crystals isomorphous with the magnetic ones, was proved to be a general law of action. Faraday as a Discoverer They point out that the apparent repulsion of diamagnetic substances is due to the fact that they are less paramagnetic than the oxygen of the air in which they are suspended. Beacon Lights of History, Volume 14 The New Era; A Supplementary Volume, by Recent Writers, as Set Forth in the Preface and Table of Contents But if nitrogen be really diamagnetic, then a bubble or bulb filled with the dense gas will overcome one filled with the rarer gas. Faraday as a Discoverer The fact, however, of this not being the case, proves that these molecular currents are not the mechanism by which diamagnetic induction is effected. Fragments of science, V. 1-2 It seemed as if the crystal were compounded of two diamagnetic bodies of different strengths, the substance being more strongly repelled across the magne-crystallic axis than along it. Faraday as a Discoverer He also proved that the amount of the rotation is proportional to the length of the diamagnetic through which the ray passes. Faraday as a Discoverer He believed that when a diamagnetic substance is brought near to the north pole of a magnet, a north pole was developed in its approached end, and that therefore repulsion occurred. Beacon Lights of History, Volume 14 The New Era; A Supplementary Volume, by Recent Writers, as Set Forth in the Preface and Table of Contents All the tissues of the human body, the blood—though it contains iron—included, were proved to be diamagnetic. Faraday as a Discoverer So far an identity of action was established between magnetic and diamagnetic bodies. Faraday as a Discoverer Oxygen, in various media, was strongly attracted by the magnet; in coal-gas, for example, it was powerfully magnetic, whereas nitrogen was diamagnetic. Faraday as a Discoverer Nitrogen, in fact, acted 'like space itself'; it was neither magnetic nor diamagnetic. Faraday as a Discoverer The majority of physicists, however, at the present time, do not believe in the existence of a diamagnetic polarity. Beacon Lights of History, Volume 14 The New Era; A Supplementary Volume, by Recent Writers, as Set Forth in the Preface and Table of Contents Might not the apparent repulsion of diamagnetic bodies be really due to the greater attraction of the medium by which they are surrounded? Faraday as a Discoverer He speaks of and illustrates by sketches, the deflection, both convergent and divergent, of the lines of force, when they pass respectively through magnetic and diamagnetic bodies. Faraday as a Discoverer In all cases, the line which in a diamagnetic crystal set equatorially, always set itself in an isomorphous magnetic crystal axially. Faraday as a Discoverer In a mathematical investigation of the subject, published in the Proceedings of the Royal Society for 1856, Sir William Thomson arrives at the conclusion that the 'diamagnetic' is in a state of molecular rotation. Faraday as a Discoverer During this investigation Faraday observed some phenomena that led him to a belief in the existence of another form of force, distinct from either paramagnetic or diamagnetic force, which he called the magne-crystallic force. Beacon Lights of History, Volume 14 The New Era; A Supplementary Volume, by Recent Writers, as Set Forth in the Preface and Table of Contents Water is diamagnetic, sulphate of iron is strongly magnetic. Faraday as a Discoverer But this character of space is not of the same kind as that which, in relation to matter, we endeavour to express by the terms magnetic and diamagnetic. Faraday as a Discoverer That is to say, while in ordinary magnetic influence the exciting pole excites adjacent to itself the contrary magnetism, in diamagnetic bodies the adjacent magnetism is the same as that of the exciting pole. Faraday as a Discoverer He therefore subsequently abandoned it, and maintained the non-polarity of the diamagnetic force. Faraday as a Discoverer The same result was obtained independently, and extended to various other bodies, magnetic as well as diamagnetic, and also to compressed substances, a little subsequently by myself.
