2 Pcs Keychain Neodymium Magnet for Testing Coins, Jewellery, Brass, Gold, Silver

<ul><li><div>These keychain magnets offer strong neodymium magnet power in handy keychains. They are perfect for jewelers, recyclers, coin dealers, or anyone that needs a convenient, easy-to-carry magnet to test for iron, nickel, or cobalt content. Featuring a durable N52 neodymium magnet housed in a nickel plated metal shell, each keychain magnet has a pull force of over 3 pounds.</div></li><li><div>Determine if jewellery is silver or gold plated by testing if ferrous metals are used as the base metal (excluding some nickel alloys). If a magnet responds to jewellery, it is not fine silver or anything near pure gold. The same is also true of brass and bronze antiques. If the magnet sticks to it, it is likely just brass plating over steel or iron.</div></li><li><div>This strong magnet is very handy for testing industrial metals for recycling. The keychain magnet features a powerful 12mm N52 grade (3 lbs minimum pull strength) neodymium rare earth magnet encased in a nickel-plated steel housing for durability and comes with a stainless steel split ring.</div></li><li><div>This magnetic keychain is strong, small, light in weight, and easy to carry. You can put it in your pocket or purse when you go out. It provides you with a versatile multi-functional magnetic testing tool.</div></li></ul>
