The strongest diamagnetic substance known is bismuth, its susceptibility being--0.
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.
The more feebly magnetic bodies are classed as paramagnetics, and those which behave as described above are called diamagnetic substances.
The action of bismuth, the strongest diamagnetic substance, is weak when compared with the magnetic action of iron.
A diamagnetic body is one which is not so magnetic as the medium in which it is suspended.
These rays impinge upon a diamagnetic surface which is concave.
All are diatomic, diamagnetic and positive; the corresponding group consists of sulphur, selenium and tellurium, also all diatomic and diamagnetic, but negative.
The corresponding group contains phosphorus, arsenic and antimony: bismuth also belongs to it, but was not examined; they are triatomic, diamagnetic and negative.
The first group is paramagnetic and positive; the corresponding one is diamagnetic and negative.
The well-known division of diamagnetic and paramagnetic depends generally on this fact, or on an analogous action on molecules, as may be seen in the accompanying diagrams.
The former he called paramagnetic and the latter diamagnetic bodies.
In all cases, the line which in a diamagnetic crystal set equatorially, always set itself in an isomorphous magnetic crystal axially.
Might not the apparent repulsion of diamagnetic bodies be really due to the greater attraction of the medium by which they are surrounded?
So far an identity of action was established between magnetic and diamagnetic bodies.
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.
That the force which does so is therefore 'distinct in its character and effects from the magnetic and diamagnetic forms of force.
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.
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.
With that admirable instinct which always guided him, Faraday had seen that it was possible, if not probable, that the diamagnetic force acts with different degrees of intensity in different directions, through the mass of a crystal.
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.
The fact, however, of this not being the case, proves that these molecular currents are not the mechanism by which diamagnetic induction is effected.
Weber is obliged to suppose that the molecules of diamagnetic bodies are surrounded by channels, in which the induced molecular currents, once excited, continue to flow without resistance.
This metal is a better conductor of electricity, but less strongly diamagnetic than bismuth.
Footnote: This theory breaks down when applied to diamagnetic bodies which are repelled by magnets.
The science which treats ofdiamagnetic phenomena, and of the properties of diamagnetic bodies.
M represents the main and N the shunt magnet, both securely fastened to the base A, which with its side columns, S S, are cast in one piece of brass or other diamagnetic material.
When magnetic force acts on any medium, whether magnetic, diamagnetic or neutral, it produces within it a phenomenon of the nature of a flux or flow called magnetic induction (Maxwell, loc.
To account for diamagnetism, Weber supposed that there exist within the molecules of diamagnetic substances certain channels around which an electric current can circulate without any resistance.
In all cases however it is the diamagneticcondition that is initially set up--even iron is diamagnetic--though the diamagnetism may be completely masked by the superposed paramagnetic or ferromagnetic condition.
The principle of Weber's theory, with the modification necessitated by lately acquired knowledge, is the basis of the best modern explanation of diamagnetic phenomena.
Kappa] of other diamagnetic substances at different temperatures.
When the two electrodes are ferromagnetic, the direction of the current through the liquid is from the unmagnetized to the magnetized electrode, the latter being least attacked; with diamagnetic electrodes the reverse is the case.
Fleming and Dewar to suggest the probability that the diamagnetic susceptibility varies inversely as the temperature between -182 deg.
Thus, for example, a tube containing a weak solution of an iron salt will appear to be diamagnetic if it is immersed in a stronger solution of iron, though in air it is paramagnetic.
For alldiamagnetic substances, except antimony and bismuth, the value of [Kappa] was found to be independent of the temperature.
The permeability of most material substances differs very slightly from unity, being a little greater than 1 in paramagnetic and a little less in diamagnetic substances.
Oxygen, which (tried in the air) is powerfully magnetic, becomes diamagnetic when heated.
On the Diamagnetic conditions of Flame and Gases, by Michael Faraday.
Its diamagnetic state shows, in a striking point of view, that gases, like solids, have peculiar and distinctive degrees of diamagnetic force.
On the Diamagnetic Conditions of Flame and Gases: Philosophical Magazine, 1847, p.
In the first example given we have an exhibition of magnetic force, while in the last we have a striking display of the diamagnetic power.
Faraday’s paper will show this:-- Nitrogen being acted on was manifestly diamagnetic in relation to common air when both were of the same temperature.
Faraday: On the Diamagnetic character of Flame and Gases.
Carbonic oxide was carefully freed from carbonic acid before it was used, and it appears to be more diamagnetic than carbonic acid.
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.
He regarded the first class of substances as attracted, and the second class as repelled, and called them respectively paramagnetic and diamagnetic substances.
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.
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.
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.
The majority of physicists, however, at the present time, do not believe in the existence of a diamagnetic polarity.
Diamagnetic liquids, such as solutions of salts of bismuth and antimony, in a similar manner, arranged the greater part of their mass in positions at right angles to this direction, or equatorially.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "diamagnetic" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: magnetic; polar; repellent; repelling; repulsive
