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.

Magnetic slide size (magnets): 50mm x 200mm
Magnetic slide size (folded): 215 mm x 60mm x 12.3mm
Approximate weight of the folded magnetic slide with magnets: 450g
