Test Three: silver and gold are not magnetic — a coin that sticks or jumps toward the magnet is wrong, full stop, no appeal. Video 05 shows the tilt/slide demo (genuine silver slides slowly via eddy currents; steel-core fake sticks or drops). The book prefers the dangle test (magnet on a string) for sensitivity and repeatability. Critical framing: the magnet is a filter, not a verdict — a fail condemns, but a pass only permits continuing to the next test. Non-magnetic fakes (copper, zinc, lead alloys) and correct-alloy fakes sail through.
