We know that electromagnetic induction takes place also when a
conductor is moved across a magnetic field in such a way that, as the
technical term goes, it 'cuts' the field's lines of force. Whereas the
process discussed above is employed in the transformer, this latter
process is used in generation of electricity by dynamo. We have seen
that a magnetic field imparts to the relevant part of space qualities
of density which otherwise prevail only in the interior of solid
masses. We remember further that the appearance of electricity, in the
two other modes of generating it, is caused by the loosening of the
coherence of the material substance. A similar loosening of the
coherence of the magnetic field takes place when its field-lines are
cut by the movement of the conductor across it. Just as heat occurs
when we move a solid object through a liquid, electricity occurs when
we move a conductor across a magnetic field. In each case we interfere
with an existing levity-gravity relationship.

Having established thus far the picture of both electricity and
magnetism which shows each as an outcome of certain levity-gravity
interactions, we now ask how, in particular, negative and positive
electricity on the one hand and north and south magnetism on the other
are determined by these interactions. Let us again begin with
electricity.

We remember that Galvani was led to his observations by the results of
Walsh's study of the electric fishes. While Galvani clung to the view
that in his own experiments the source of the electrical force lay
within the animal bodies, Volta saw the fallacy of that. He then
conceived the idea of imitating with purely inorganic substances the
