state of space gives rise to the appearance of an electrical field.
This process is called electromagnetic induction. With its discovery,
the generation of electricity through friction and in the galvanic way
was supplemented by a third way. By this means the practical use of
electricity on a large scale became possible for the first time. If our
picture of the two earlier processes of generating electricity is
correct, then this third way must also fit into the picture, although
in this case we have no longer to do with any direct atomization of
physical matter. Our picture of magnetism will indeed enable us to
recognize in electromagnetic induction the same principle on which we
found the two other processes to rest.

Magnetism is polarized gravity. Hence it has the same characteristic of
tending always to maintain an existent condition. In bodies subject to
gravity, this tendency reveals itself as their inertia. It is the
inertia inherent in magnetism which we employ when using it to generate
electricity. The simplest example is when, by interrupting a 'primary
current', we induce a 'secondary current' in a neighbouring circuit. By
the sudden alteration of the electric condition on the primary side,
the magnetic condition of the surrounding space is exposed to a sudden
corresponding change. Against this the magnetic field 'puts up' a
resistance by calling forth, on the secondary side, an electrical
process of such direction and strength that the entire magnetic
condition remains first unaltered and then, instead of changing
suddenly, undergoes a gradual transformation which ideally needs an
infinite time for its accomplishment (asymptotic course of the
exponential curve). This principle rules every process of
electromagnetic induction, whatever the cause and direction of the
change of the magnetic field.
