Magnetic Slide - Fake Gold/Silver Coins & Bars Tester

Magnetic Slide (Fake Gold/Silver Coins & Bars Tester) The magnetic slide detects fake gold/silver through an 'intrinsic property' known as diamagnetism. This produces an effect called the Eddy Current Brake. ----- An example video showing how it works (not made by me): https://www.youtube.com/watch?v=pvsSEkb87YY ----- Printed parts: 1.
