Neodymium Magnets React With Copper? Still Useful For Finding Precious Metals?
- Published on Jun 26, 2013
The plated bar seems to make the magnet slide a bit slower.. However it was very minimal. Which means a small amount of plating can fool a small magnet. So you should likely get a larger/stronger/thicker magnet for testing larger bars..
Neodymium magnets react the exact same way with copper as with gold, silver platinum, palladium, rhodium, and many other metals. So it could be possible to mix different metals with each other to make a cheaper metal which cannot be distinguished. How would you know if your platinum is not 30% palladium?
