This is a device which makes the use of Fleming's right hand
rule which if drawn would represent in all directions in a three
dimension space that is [up,down] [left,right] [front,back]
Take one line to represent the direction of the magnetic field
another to represent the flow of the current and the final one
to represent the direction of motion. This holds true from all
combinations of magnets, current and direction in any form of
motor.
A motor usually consists of a stationary magnetic field called
the stator and in the middle a rotating magnetic field called
the armature fed by a direct current alternated by commuter.
In this design there is no moving core except the motion of the
liquid salty water.
Construction
Please remember this only an Experimental Idea
Obtain a P.V.C. pipe and cut to length desired. drill two
holes directly opposite one another each side of the pvc and
insert brass nuts and bolts
These will be the means by which electrical current will flow
from one contact through the water and to the other contact.
Seal around bolt holes so that they cannot leak water. Take
two leads from these points.
Now mount two magnets permanent or electro magnets over top of
the contacts and fix into position.
If you wish to use permanent magnets go to a local vehicle
wrecker and obtain a windscreen wiper motor .
Disassemble the motor usually with a hack saw and remove the
armature section. You should know have easy access to the curved
magnets inside.
These will fit ideally around the pvc tubing of the correct size
and could be held in place with electrical insulation tape.
Set up tube and fill with salty water connect up the field coils
if not a permanent magnet and pass a current through the
contacts.
With the correct voltage, current and water conductivity. This
you will need to determine by experimentation.
Water should then flow in one direction or the other.
With greater magnetic strength and wider current flow across the
direction of water flow ,this could conceivable be used as a
device to propel an aquatic vehicle across water.
Nuclear power stations already employ something similar in the
reactors.

I came across this idea in some papers I received The idea seems
to originated from some one called Richard Lefors Clark Ph.D
dated 18/3/86 4015 Crown Point drive P-3 San Diego CA 92109
He seems to suggest a way to generate a strong diamagnetic field
by pumping water through copper tubing wound in a spiral helix
using a normal water pump.
He also seems to suggest that by putting four to six coils on a
platform and then turned upside he could levitate the platform.
Professor Clark
suggests that if put a normal electric current through the tube
we get a strong normal magnetic field.
Suggests also that the connection of diamagnetism and
electrical effects has hidden the true nature and utility of
diamagnetism.
For evidence he quotes an experiment performed by Oersted
Now with water flow in the copper coil only
Connect a loop of wire in a complete circuit with an ammeter.
Move the copper wire coil close to the water carrying helix
copper at close range.
No magnetism but electrical current is produced in the ammeter
circuit.
He also seems to suggest that we need high speed flow pumps and
directional flow coils to improve the design.
Maybe the two designs in this article could be linked to create
the above flow pumps.
Wind coil mentioned in this second article like normal dc coils
are wound. Start at one end and tightly wind down in spiral path
until one layer is finished and in one rotation back to the top
then back down again as at the start.
Editor's note
If what the professor suggests is correct, think of what kind of
new motors and generators could be made, perhaps better
performing than those we have now.
