If a magnet responds to jewelry, it is not fine silver or anything near pure gold. The same is also true of brass and bronze antiques, many are just brass plating over steel or iron. This strong magnet can also be used to determine polished aluminum from stainless steel in most cases, and is very handy for testing industrial metals for recycling.\u003cbr\u003e\u003cbr\u003eThe keychain magnet features a powerful 28mm N52 grade (16 lbs\/71 Newtons minimum pull strength) neodymium rare earth magnet encased in a plated steel housing for durability and comes with a stainless steel split ring.\u003cbr\u003e\u003cbr\u003eProduct Specifications\u003cbr\u003eType: Neodymium Magnet Keychain\u003cbr\u003eMaterial: N52 Neodymium\u003cbr\u003eDimensions: 1.1 inches wide at its widest point x 2.65 inches long (28 x 67.5 mm)\u003cbr\u003eWeight 2 oz (56 g)\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePackage Dimensions:\u003c\/b\u003e 6.0 x 4.0 x 1.2 inches\u003c\/p\u003e","brand":"EnMagnet","offers":[{"title":"Default Title","offer_id":44710475956269,"sku":"B0D9PQ4JG4","price":38.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0714\/9541\/7901\/files\/51bgYWaAFFL.jpg?v=1773441844","url":"https:\/\/cozymarts.shop\/products\/extra-large-keychain-magnet-tester-for-gold-silver-jewelry-precious-metals-with-n52-rare-earth-neodymium-magnet","provider":"Cozymarts","version":"1.0","type":"link"}
