Abstract.
This article considers electromagnetic
origin of gravity and describes techniques to
generate gravitational field that has the
opposite sign to that of Earth.
Introduction
Define “spin current”
g1835
g3046
g3404g1869g2033
, where
g2033
is the
angular velocity of spin of a charge
g1869
. Spin
current
g1869g2033
, measured in Amperes [A] , does not
flow through a conductor, but “exists” when a
charge
g1869
spins.
Spin currents are present in every atom and
most components of the Universe, but they
seem omitted in the current theory of
electromagnetism.
The remainder of this article demonstrates that
spin current
g1869g2033
may be responsible for
existence of the force that we now call “gravity”
and that we should be able to engineer practical
gravity control devices.
Hypothesis
Let’s consider that the average value of the
“gravitational” force
g1780
g3552
g2929
between two objects as a
cumulative result of average spin currents
g1835
g3046g2869
g3554
uni0061uni006Euni0064g1835
g3046g2870
g3554
in each object as follows:
g1780
g3552
g2929
g3404g3398g1827
g2868
g2870
g1835
g3046g2869
g3554
g1835
g3046g2870
g3554
g1870
g2870
g1818
uni0072
g4666uni0031g4667
where r is the distance between objects,
g1818
g2928
is a
unit vector that defines direction, and
g1827
g2868
g2870
is a
positive constant that we shall try to estimate
later on in this article.
This equation is as elementary as the definition
of Ampere that links mechanical forces to
electromagnetism.
In line with tradition we can represent the force
g1780
g2929
using average spin current fields
g1845
g4632
g2869
uni0061uni006Euni0064g1845
g4632
g2870
as
follows:
g1780
g3552
g2929
g3404g3398g1827
g2868
g2870
g4678
g1835
g3046g2869
g3554
uni0072
g4679g4678
g1835
g3046g2870
g3554
uni0072
g4679
g1818
uni0072
g1565g3398g1827
g2868
g2870
g1845
g4632
g2869

g4666uni0032g4667
Force
g1780
g3552
g2929
exists when both
g1845
g4632
g2869
uni0061uni006Euni0064g1845
g4632
g2870
exist and
interact.
Spin current field potential
Consider a field potential
S
due to spin current
g1869g2033
of an elementary charge, say an electron.
Electrical field potential around a charge is
known to be isotropic, i.e. identical in all
directions. In contrast, field potential
S
should
be expected to be anisotropic.
On the basis of astronomic observations of
spinning systems, specifically a presence of
collimated symmetric jets observed during star
formation process along axes of spin [2], it is
reasonable to expect that the spin current field
S
is restricted to a symmetric cone defined by a
solid angle
g2011
g2868
around the spin axis.
