Permanent Magnet Used in Salvaging Industry

Neodymium has the most significant magnetic power, they can be used for underwater or bottom well salvaging, magnetic salvaging can be seen in the following places:

Shipyards often have steel plates falling to the bottom when building ships. Workers can use neodymium salvage magnets, like double-sided neodymium fishing magnets, that have strong magnetic power to pull up them to reduce losses

In oil fields, a bit that falls under a well can be pulled out by a powerful salvage magnet

On ships, salvage magnets are often seen on boats, they are used by the crew to pick up tools that have fallen to the bottom

Wholesale fishing magnets are also used as playthings for outdoor enthusiasts.
