Permanent Magnet Propulsion System
A propulsion system for a train that uses permanent
magnets mounted on a rotating iron cylindrical plate carrying
a radial current in order to create a spacetime curvature
distortion which pulls the locomotive along the track.
BRIEF SUMMARY OF THE INVENTION
[0001] This invention is a propulsion system for a train
that utilizes spinning cylindrical magnets in order to create
a spacetime pressure distortion ahead of the vehicle that
pulls the locomotive along the track.
BACKGROUND OF THE INVENTION
[0002] At the present time, referring to FIG. 1, proposed
permanent magnet propulsion systems use a dual railway track
(A) supporting a series of coil windings (B) located along the
track. The vehicle is attached to two permanent magnets (D)
between steel pole pieces (C). The north pole of each magnet
faces the interior pole piece such that the magnetic flux path
(E) follows the center pole piece up through the railway bed
and then back to the south pole of the magnet. As the magnets
move along the track, the coil windings are activated at the
correct time by Hall sensors. With the coil energized as a
north pole, the permanent magnet north pole is repelled which
drives the vehicle along the track The problem with this
design, and other similar designs, is that it is not practical
to wind huge numbers of sensor-activated electrical coils
along a steel track.
[0003] From Einstein's General Theory of Relativity, it is
known that a spacetime curvature pressure develops
perpendicular to direction of vibration of the electric and
magnetic field. As an example, the photon has an electric
field vibrating in the vertical y-direction and a magnetic
field vibrating in the horizontal x-direction. The spacetime
curvature pressure is therefore along the z-axis of radiation
which pushes the negative mass of the photon along. Thus in
order to create a spacetime curvature pressure in the
z-direction along the track which would pull the train
forward, a magnetic flux density field is required in the
radial direction.
[0004] Referring to FIG. 2, four equally-spaced north
permanent magnets (B) surrounding a centrally-located south
permanent magnet (C) are mounted on an iron cylinder which
acts as the radial flux return path. The magnetic flux density
field (D) is in the radial direction from the north pole to
the south pole. In order to provide strength, the magnets are
molded onto a steel shaft and coated with epoxy so that they
don't rust. During the molding process, a capacitor-discharge
magnetizer is used to create the magnetic field of the magnet.
[0005] In Cartesian coordinates {-ct,x,y,z}, the elemental
spacetime length ds squared is the sum of the squares of the
incremental lengths {cdt,dx,dy,dz}
(ds)<2> =-(dt)<2> +(dx)<2> +(dy)<2>
+(dz)<2 >
where the speed of light c is unity. The coefficients
(-1,1,1,1) of this equation make up the g metric 4*4 tensor
[mathematical formula - see original document][mathematical
formula - see original document]
[0006] The Faraday electromagnetic tensor contains the
magnetic fields which determine how the spacetime length ds is
curved. For a magnetic flux density field in the x-direction,
Bx, and a magnetic flux density field in the y-direction, By,
the Faraday tensor is [mathematical formula - see original
document][mathematical formula - see original document]
The stress-energy-momentum tensor T, which determines how
space is curved, is calculated from the following equation
[mathematical formula - see original document]
The stress-energy in the z-direction ahead of the locomotive
is [mathematical formula - see original document]
where the sum of the squares of the fields in the x and y
directions is the radial B field. In Einstein's General
Relativity Theory, the curvature G tensor is equal to the
stress-energy tensor divided by 8[pi]. The G tensor is the
curvature of space having units of inverse radius squared.
[mathematical formula - see original document]
Therefore the curvature Gzz generated along the z-direction
ahead of the train is proportional to the square of the
magnetic flux density field [mathematical formula - see
original document]
where G is Newton's gravitational constant (not to be confused
with the curvature tensor), [epsilon] is the linear
capacitance of space, and c is the speed of light. The linear
mass of space [Omega] is the speed of light c squared divided
by the gravitational constant G, so that the equation can be
written as [mathematical formula - see original document]
where the conversion factor is the square of the magnetic
vector potential A [mathematical formula - see original
document]
which is actually the momentum per charge. Therefore the
curvature equation can be written as [mathematical formula -
see original document]
This equation shows that it is necessary to create a magnetic
vector potential together with the radial magnetic flux
density field in order to create a curvature of space. Looking
at the units of A shows that it is a mass momentum per charge
[mathematical formula - see original document]
or a mass m rotating with angular velocity c) per current
along the radius. In terms of the invention, what this means
is that the mass of the iron cylinder has to be rotating and
there has to be a radial electrical current I in order to
produce the linear charge along the radius. The differential
mass dm depends on the circumference times the differential
radius dr, the mass density p, and the length L of the
cylinder
dm=[rho]2[pi]rLdr
so that the magnetic vector potential becomes [mathematical
formula - see original document]
The value of A for the iron cylinder is [mathematical formula

What makes this possible is that the new N-machines can easily
generate a minimum of 6 million amps which is twice the value
of the electrical current above.
[0007] Referring to FIG. 3, the assembly consists of a large
induction motor (A) mounted on the train's base plate (B)
driving a motor shaft (C) attached to the iron cylinder (D).
The shaft is held in place by two thrust bearings mounted in
two pillow blocks (E,F). The current-generating N-machine (G)
is electrically connected by a copper bus (H) to a
copper-beryllium brush (I) on the motor shaft with a similar
return brush (J) on the edge of the iron cylinder. The current
(K) flows through the motor shaft to the center of the
rotating cylinder and then radially outward to the edge. The
magnetic flux density flows from the north poles of the outer
permanent magnets to the central south pole, along the central
magnet to the center of the rotating cylinder and then
radially outward to the south poles of the outer magnets.
[0008] The thrust F developed is the radius of curvature of
spacetime rc calculated above times the magnet flux density
field times the current I [mathematical formula - see original
document]
Using conservation of tensor coordinates, the radius of
curvature is in the z-direction, the magnetic flux density
field is in the radial direction and the current is in the
radial direction
F<z> =x<z> BrI<r >
where the radial indices cancel, leaving the z-index as the
direction of the force.
SUMMARY OF THE INVENTION
[0009] It is the object of this invention to create a
spacetime curvature in front of a train locomotive in order to
pull the vehicle along the track It is known from
gravitational physics that a spacetime curvature is generated
perpendicular to the direction of vibration of the electric
and magnetic field. A radial magnetic field, which can be
produced by permanent magnets attached to the flat faces near
the rim of a iron cylinder rotating about the z-axis, will
create a curvature in the z-direction. Four cylindrical
north-pole-oriented magnets produce a radial magnetic flux
density with is channeled into a central cylindrical
south-pole-oriented magnet. The flux lines then flow radially
outward through the steel rotating cylinder and reconnect with
the south poles of the four outer magnets. The rotating iron
cylinder generates the equivalent of a magnetic vector
potential when an electrical current flows from the center of
the cylinder to the edge. This current is generated by an
N-machine current generator. The square of the magnetic flux
density divided by the magnetic vector potential is equal to
the spacetime curvature. The square root of the inverse of the
spacetime curvature is the radius of curvature. The thrust
developed is this radius of curvature times the magnetic flux
density field times the current.

DETAILED DESCRIPTION OF THE INVENTION
1. The permanent magnets are made of neodymium-iron-boron
material which is heated to its melt temperature and injection
molded around a steel shaft threaded at one end while at the
same time a pulsed magnetic field is applied to the material
using a charge-discharge magnetizer. Because of the iron in
the material, a coat of epoxy is applied to the magnet in
order to protect it from the environment. Holes are drilled
into the iron plate 90[deg.] apart near the rim, threaded, and
then the steel shaft with the magnet is then inserted. Another
hole is drilled and tapped in the center of the circular plate
for attaching the south pole magnet which is used as the
return path for the magnetic flux.
2. Another easier way to make the magnets is to purchase short
lengths of tubular NdFeB magnets and then stack them on the
steel shaft with a cylindrical iron pole piece on the end of
the shaft. The pole piece then holds the magnets down in place
when the shaft is threaded into the plate.
3. Referring to FIG. 4, the propulsion system is mounted
inside the train cabin such that the rotor/magnet assembly
extends out in front of the locomotive where the spacetime
curvature is generated.
