Last year a friend of mine sent me the construction diagrams of a simple
device, a motor, which the inventor (an aquaintance of his) claimed worked
with no input power. On receiving this information I was at a loss to
replicate the fundimental design criteria of the device.
The inventor claimed that by passing a heavy current through a lenght of
steel wire, in fact the inventor used steel welding rods in his
construction, he was able to obtain a residual magnetism in the wire. Well,
I zapped steel wire with all sorts of currents but could not create any
residual magnetism in steel wire of all sorts of grades.
The device itself simply consists of two steel welding rods which are bent
in such a way that each forms a loop with a short axle. When these two
loops of wire are made so that one fits inside the other (one loop smaller
than the other) and magnetised with a heavy current (the relative
orientation of the current through the loops was important), it is claimed
that a torque exists between the two wire loops. if one of the loops is
free to rotate it will do so. Obviously a torque may exist between these
two loops while the current wis on, but the inventor insisted that the
current was only used to magnetise the wire. Spooky, hey?
The inventor swore blind that he had built the device and that it worked as
he stated. Unfortunately, I was unable to get past first base with my
replication.
How could one permenantly magnetise a lenght of steel wire with an applied
heavy current?
Bill.
