Best use for neodymium magnet, locate fake Chinese wires made of iron

[Kiriakos GR]

Within 2024, here comes one new recommendation about using a neodymium magnet as scam detector.

This is a recommendation, for eBay and Aliexpress buyers of no-name test leads.
Some scammers in Mainland China, they did find the way to form regular iron in to a multi-strand wire.
And they also paint the iron, so this to look similar to copper.

Product in question, is the assembled pair of alligator clips in to multiple colors. 

My recommendation, buy only alligator clips, and re-use wires from dead computer PSU.
Especially the very old PSU they was had pure copper wires in their 20 pin harness.
