The excerpt represents the core issue or deciding factor on which you must meditate, and is drawn from Faraday as a Discoverer by John Tyndall: inclines, but still with caution, to the opinion that the action of
a magnet upon bismuth is a true and absolute repulsion, and not
merely the result of differential attraction. And then he clearly
states a theoretic view sufficient to account for the phenomena.
'Theoretically,' he says, 'an explanation of the movements of the
diamagnetic bodies, and all the dynamic phenomena consequent upon
the action of magnets upon them, might be offered in the supposition
that magnetic induction caused in them a contrary state to that
which it produced in ordinary matter.' That is to say, while in
ordinary magnetic influence the exciting pole excites adjacent to
itself the contrary magnetism, in diamagnetic bodies the adjacent
