Ally, both involving the poles and above or beneath them, with magnetic substances often behaving the opposite to diamagnetic, and on cubes of distinct woods. He employed the fact that diamagnetic bars set axially between flat poles (though not pointed poles) to deduce that the line joining the centre of two flat poles may be the line of minimum force. Faraday remarked that `it was conceded on all hands that the explanation was erroneous which Pl ker had given’, but in saying that `did not imply that as the slightest disparagement to that philosopher’ because `it was by means of the mist of error that probably the most crucial discoveries had to be made’. He asked his mathematical good friends, Whewell and other people, for assistance in explaining the law of distribution of force inside the magnetic field, if it was recognized. Whewell turned to Thomson, who stated that a totally uniform field, as opposed to an approximation, could only be obtained inside a magnet, but this will be hard to239 F. C.

Thomson has actually backed out of just about every single position he has assumed in regard to the phenomena of diamagnetism and magnecrystallic action. And he has accomplished so leaving the public to suppose that he had been misconstrued or misapprehended which tact may perhaps possibly increase his reputation together with the general public, but within the private opinion of me at the very least 
will not add a whit to his nobleness.249 This paper presented experiments with MedChemExpress Fumarate hydratase-IN-1 bismuth to test irrespective of whether diamagnetic bodies possess a polarity opposite to iron (Weber) or the same (von Feilitzsch), or have no polarity (Faraday, Thomson). He showed that the repulsive force increases because the square from the strength with the influencing magnet, so it depends on joint action with the magnet and diamagnet, and that the excitement evoked by one particular pole in a diamagnetic body enables a pole of opposite high quality to repel it. He also showed the value of structure, in that a bar of bismuth with its planes of principal cleavage parallel to its length sets perpendicularly to magnetic lines of force (a `normal’ diamagnetic bar), and if transverse sets parallel. The former behaves because the precise opposite of a bar of iron, and there is certainly precisely the same antithesis when the bars are placed in an electrical field inside helical coils. This and simila.
