Silver is the most conductive material known to man. Where losses due to resistance were critical, silver wires, or silver plated wires were used instead of copper, in applications such as coils in detector circuits where we are dealing with very small currents.

Hi All
In regards to silver wire:
Towards the end of WWII, copper was so rare, actually some airplanes were built using solid silver wires.  It would then make it natural that they would have some silver wire on hand to repair damaged airplanes.  If copper wire were available, I am sure they would have used that instead.

Salvage companies in the know, had the serial numbers of the airplanes that had silver wire.  They would bid for the salvage rights knowing the secret of silver wires inside.

My feeling is that silver wire was used because of the lack of copper wire.  No other reason.

HI Michelinho

Nice build.  You don't say, but I would suggest you try and get the natural self resonance of the circuits to be around 175Khz to 180Khz.  Maybe you could induce the output of a signal generator and sweep through the frequencies?  You want the highest output readings to be around 180Khz or so.  It could be that physical parameters of your setup is not allowing self resonance to be near that frequency?  Once it is tuned to 180Khz, unhook the signal generator and see if you output is higher than what you currently get?

Just an idea.

I doubt that the reason for using silver was a shortage of copper. The common substitute for copper wire in war time was aluminium. If they used silver wire in the planes it was for reasons other than unavailability of copper. Silver in wartime as well as in peacetime is a lot scarcer.

Hi all,

As for the aluminium wire, it is not recomended for use where there is lots of vibrations because it breaks it is also not to be used near salt water. So it could be why the use of silver which was plentiful after cleaning out Europe for precious metal and ware.

Thanks. That is what is said in the British papers and by Aspen also, 179-180 Khz. My signal generator is for audio tests and only goes to 20 Khz so I have to wait for my son-in-law to bring his, meanwhile, I'll do new magnets with a different shape and higher magnetic flux for more tests.

Take care,
