The influence of traction in diminishing the susceptibility of nickel was first noticed by Kelvin (W.
The mere reading of accounts of seances developed the peculiar susceptibility in some persons, while others, who became mediums ultimately, did so only after prolonged and patient waiting.
The requirements of barley within the soil, and its susceptibility to the external influences of season, are very similar to those of its near ally, wheat.
The magnetic susceptibility expresses the numerical relation of the magnetization to the magnetizing force.
Villari in 1868 that the magnetic susceptibility of an iron wire was increased by stretching when the magnetization was below a certain value, but diminished when that value was exceeded; this phenomenon has been termed by Lord Kelvin, who discovered it independently, the " Villari reversal," the value of the magnetization for which stretching by a given load produces no effect being known as the " Villari critical point " for that load.
