1000LB Fishing Magnet Neodymium Pot Magnets are a type of powerful neodymium magnet used for magnetic fishing. They are usually designed with a steel shell to enhance their durability and magnetic performance. 1000LB represents its amazing 453 kg (1000 pounds) vertical pulling force, which is equivalent to lifting half a car from the bottom of the water. The core of this magical power is neodymium, known as the "king of magnets" - a rare earth permanent magnet material, whose magnetic energy product is more than 10 times that of traditional magnets.
