content: Checkout this videoSure enough, went around the workshop and we found a few alligator cables and USB cables were ferrous!Lots of open mouthed engineers not believing their eyes. What will China think of next!

content: It's not new either, personally I fell vicitim for this in 2013.Bought three types of test leads from three different EBAY vendors, all magnetic.

content: There is another scam, and that does not come from china:Cables having less than advertised crosssection: They have 20% less! And those not just from some small shops, and even in germany (4 out of 5 tried to scam me)!

content: the way to do it is to measure 1 strand with a micrometer and use the CSA formula after you count the strands. annoying but its the only certain way

content: I think its more direct that when you get a specified wire, you measure it with the most simple easy tool to use, unless its 600 strand.you strip 1cm of wire. count how many strands. then measure one with a micrometer.Thats the only way you will find it can be done accurately in a normal shop.ALot of the people here facing fake wire problems (i.e. electricians) don't have measurement microscopes or accurate scales or even kelvin. A micrometer is something that is ubiquitous.Here is a real situation: you routed a solar cable on the roof and got second thoughtsI am realistic. Have you ever dealt with installed wiring before? Some one leaves and your left with 8 inches sticking out of a wall, barely enough to get 1 rewiring out of it.If you actually followed the fake wire problems on the forum, you would see how the big trouble actually starts.

content: Electricians typically have fucked up test leads on a 3.5 digit fluke that won't read resistance under 1 ohmhammer and chisel, no, im not in chicago.

content: I checked the ones I recently bought in the Arrow electronics sale. The Adafruit ones are folded and unsoldered. But at 20 cents or so for 10 leads I ain't complaining. There are none left.The Meuller Electric BU-00285 are AU$3.38 or about US$2 for a pack of 10. They are not magnetic wire and are soldered. And they are still available.https://www.arrow.com/en/products/bu-00285/mueller-electric-company?q=BU-00285
