The Uolor double-sided neodymium magnet, designed for magnet fishing, boasts a holding force of 170 kg on each side. It measures 67 mm in diameter.

Neodymium magnets are the most powerful permanent magnets in the world and are currently the most widely used in all fields. Neodymium magnets are also known as NdFeB magnets because they are composed of an alloy of neodymium, iron, and boron. Magnet fishing is a combination of ecology and treasure hunting. The magnets used are strong enough to remove large debris such as bicycle parts, guns, safes, bombs, coins, and car parts (tires, rims) from bodies of water, but many who take up this hobby hope to find rare or valuable items. Metal detector magnets are used to probe wells, rivers, ponds, etc. They are also used for other applications: construction work, DIY projects, hanging, fixing, suspending, experiments, etc. This magnet is coated with a protective layer of nickel. As for finding anything, it goes without saying that you will only find ferrous metals! But you're in for even more surprises, as magnet fishing enthusiasts also pull up everyday objects like keys, phones, and coins. Furthermore, we suggest that customers use strong glue or a threadlocker such as Locktite or plumber's tape, and frequently check the tightness of the connection to prevent the bolt from loosening.
