Product Details

Mighty-Mini Copper Keyring / Key Chain Magnet Assembly.

A powerful N52 grade neodymium rare earth magnet is encased in copper and comes with a split ring. This magnet is rated at 4 lbs of pull force.  Use it for:

• Hanging Keys; attach to your keyring and hang on any plain/painted steel surface (even stainless steel in most circumstances). It easily held a set with a large carabiner and at least 20 keys.
• Identifying and sort steel grades and metal alloys that contain iron, nickel, or cobalt
• Identifying fake/plated jewelry, which often uses steel as the base metal
• Identifying solid brass and bronze antiques (replicas are usually brass coated steel or iron)
• Magic tricks and science experiments

The copper casing protects the magnet from chipping and breaking, which are common problems with unmounted rare earth magnets. It also provides a way to carry the magnet or hang it on a peg hook.  These magnets are made in the USA. The copper will patina to a brick reddish-brown. If you would like to keep it bright, clean with Brasso, or equivalent metal polish.
