Typical magnet fishing equipment, including protective gloves, a bucket for storing catches, antibacterial hand gel, and a neodymium magnet attached to a rope. Magnet fishing is typically done with gloves, [10] a strong neodymium magnet secured to a durable rope between 15 and 30 meters (50–100 ft), and sometimes a grappling hook as a supplement to the magnet.

The flux per unit area of certain permanent magnets, particularly Neodymium-Iron-Boride and Barium-Ferrite magnets, corresponds closely with the detection range of the Ampullae of Lorenzini. The fields generated by these permanent magnets (ferrite and rare-earth types) decrease at the inverse cube of the distance from the magnet to sharks and rays.
The greater forces exerted by rare-earth magnets create hazards that may not occur with other types of magnet. Neodymium magnets larger than a few cubic centimeters are strong enough to cause injuries to body parts pinched between two magnets, or a magnet and a ferrous metal surface, even causing broken bones. [46]
A neodymium magnet of a few tens of grams can lift a thousand times its own weight, and can snap together with enough force to break bones. These magnets are cheaper, lighter, and stronger than samarium–cobalt magnets. However, they are not superior in every aspect, as neodymium-based magnets lose their magnetism at lower temperatures [52 ...
MP Materials focuses its production on Neodymium-Praseodymium (NdPr), a rare earth material used in high-strength permanent magnets that power the traction motors found in electric vehicles, robotics, wind turbines, drones and other advanced motion technologies. [11] MP Materials is listed on the New York Stock Exchange under the ticker symbol ...
A citizen who was magnet fishing in the creek on April 14 discovered a .22-caliber rifle, the GBI said in a news release Monday. The unnamed person returned to the same spot two days later and ...
