The linear magnetic current flows in the
x
-direction, that is, along the model
strike, and does not depend on
x
. This current is equivalent to an infinitely long
uniform solenoid embracing the inhomogeneous domain
V
. Its magnetic field is
confined to
V
and is zero outside
V
(the solenoid does not liberate its magnetic field
to outer space). It is obvious that the inductive magnetic field does not come up to
the Earth's surface and we observe there only the galvanic effects.
