The magnet test is a blunt triage on face-to-face buys: silver is not ferromagnetic. If a “silver” piece slaps to a strong neodymium magnet, think plated steel. It does not prove everything—yet nukes a huge chunk of junk.
Powerful neodymium delivers unambiguous pull vs fridge magnets. Handle carefully—pinch risk; never drag the edge; lift with edge protection.
What the magnet test does NOT do
- Does not replace XRF/density for exotic alloys.
- Does not grade purity if the core stays non-magnetic.
- No excuse abuse—slapping can ding soft coins.
Safe 10-second protocol
Slide magnet sideways; if it leaps, stop and log. Photo + short video help disputes.
Amazon
Pick disc magnets with pull ratings + keep away from cards / electronics.
- NdFeB > cheap ferrite for decisive tug.
- Gloves advised for N52-class pulls.
- Affiliate-ready.
