Our new gold testing magnet from CMS magnetics is a much more durable and versatile version of our regular keyring magnet. This gold testing tool measures 2.4” in height, is 3/4” at its body and 0.850” inches at the end of the cap. The embedded magnet measures 0.55” across and has a pull force of roughly 27lbs.
This magnet features a keyring at the top of the magnet that allows you to attach this to a lanyard for quick and easy access, along with a coarse-threaded removable cover that allows you to quickly and easily remove the cap of the magnet to test an item, and then easily replace it when not in use. The cap adds a 1/4" gap between the magnet and any magnetic material, which drastically reduces the strength and makes it possible to even carry this gold tester around. With the cap in place, it also gives the added benefit of being able to carry this magnet around and not have to worry about this magnet inadvertently sticking to metal surfaces.
In order to increase the effectiveness of this magnet, it’s also entirely encased in an aluminum housing that will protect the magnet from breaking or having objects stick to the magnet when not in use, along with providing enough of an area to be able to easily grip the tool.
Easily and quickly test the authenticity of gold jewelry using a super strong neodymium magnet, the strongest of its type. Faux gold jewelry is typically made of an alloy that uses iron in it which is magnetic, whereas authentic gold jewelry is made of an alloy that has no iron present and will not react to a magnetic field, no matter how strong it is. Testing a piece of jewelry couldn’t be easier or faster, simply remove the protective cover from the end of the tester and hold it up against a piece of jewelry you’re testing. If the jewelry reacts to the magnet, trace amounts of iron or other materials that react to magnets are present.
Some alternate uses of this magnetic gold testing tool include tying a string to the end of the tool and using it to pick up magnetic objects in hard to reach places, detecting studs in the wall by attracting to the nails in the studs, or other instances in which a strong magnet is needed.
