Voltage from a single piece of wire.

[ibpointless2]

So I came across something that’s got me puzzled and I’m looking for some help to figure out what is going on.

Before I begin here is a video showing what’s got me puzzled.
Voltage From a Shorted out Test Lead - YouTube

I know some this may seem stupid and could have a simple explanation to it but I can’t figure it out. It’s just a simple alligator test lead connected to my multimeter, a dead short, but its giving me voltage. To make sure I’m not crazy and my multimeter is working and not picking up RF noise I connect another alligator test lead to the meter and I get no voltage. The yellow test lead gives me voltage but the green test lead gives me no voltage, the only difference between them is that the yellow test lead is attracted to a magnet. I have another test lead that is read that show the same effect as the yellow one and it too is magnetic but it’s much harder to get the red one to give voltage, it’s like it needs to be turned?

I know many are thinking that it’s just stray AC from my house that my meter is picking up with the use of the wire. If that was the case than why is the green wire not effected? When I first discovered this I was thinking it was the AC from the house so I took the yellow wire and placed it near a CFL bulb, and many of you know it emits high voltage, and to my surprise the wire was not affected by the presence of the CFL. This idea of me picking up stray radiation from the house would hold up but no diode is used, so no I’m left scratching my head.

My mind wants to jump to conclusions like it’s something to do with the TPU or Roy J Meyers devices but my heart says it’s nothing special, but my brain doesn’t have a clue. So hopefully someone might know the answer?

That's interesting. Have you measured the resistance of the wire? My guess is there's iron in the wire and it's rusted in a couple places and the resistance has gone up between the iron oxide and iron. So you've got two dissimilar materials that then creates your voltage. If it reads 0 ohms, then I'm probably wrong...

I think you might be right. I'm trying to figure out where I got that test lead from, it was either Radio shack or Amazon.

I've got a bunch of test leads from radio shack. I checked them all after watching your video and none of them stick to a magnet...

this would be the exact opposite of your wire effect. i have a static machine i have used for years and it after certain testing just went dead not a peep of voltage out of it my friend i told about this did the same as i did with his machine and it did the same thing
he found that by rubbing the machine down with a nylon stocking it came back to life.
i have not tried this yet as i don't have a nylon stocking.
i have been told this doesn't happen to static machines but it did.
as for your wire i don't know but it seems like an opposite reaction to me what and how may be the point for study. was there something you did with that wire before you noticed this effect say some odd circuit connection.
do other wires used this way do the same thing?
just some thoughts here.

Please measure resistance of yellow wire and if magnet attact it when disconnected from meter.

It appears that you are getting a galvanic voltage from two dissimilar metals at one end of the yellow test lead.

Dont forget temperature,humidity,and certain non-conductive materiel's like plastic that create static charge. The range of a multimeter,flooring,types of shoes and various materials that are handled at the time will come into play. If the amount of electrons and protons in materials and its environment reach equilibrium you wont get much electron flow.

Try some hand made wire that attract to magnet. Besides galvanic effect, it could be normal Faraday induction cause by wire material. I think Tesla made a system that heats up material until its magnet property is lost and cool it down to regain attraction to magnet. The changing magnetic field gives energy. Can you also switch your meter to AC and see what's up?

it's the wire and the clips

Those seem to be the low budget crock clip leads those clips are iron and usually the wire itself also contains iron wire which has resistance issues.
I had some of those too and replaced all the wires with pure copper wire.

Check to see if the wire reacts to a magnet.

Using my same Innova 3300 meter, I haven't managed to replicate your experiment yet. But, my leads are different.
The clips come from Walmart, pack of 6 for $1.89 or similar and then I use ex PC power supply wires to go between. They are copper.
The clip lead ends are magnetic.
I'll see what wire around here is iron based and try it out further...kinda interested to see if a 20ft length with magnets along could indeed light an LED. All maybe helped by having an antenna property and then trialing antenna designs of different lengths.
