About Super Strong Fishing Magnet, 748 Lb Pull Rare Earth

What's Magnet Fishing Magnet fishing, also called magnetic fishing, is searching in outdoor waters for Ferromagnetic objects available to pull with a strong neodymium magnet. About Our Fishing Magnet This round base rare-earth neodymium cup magnet is made with A3 steel plate and coated with Nickel-Copper-Nickel. It’s Included eyebolt meanwhile we can remove the eyebolt , Screw it into a wall to hold tools, or position and hold lights, signs, and more. Magnet Specifications Color: Silver Model: LNJ90 Max Pull Force: 748lbs (340kg) Size: D3.54''(90mm) X T0.70''(18mm) Hole Diameter: 0.39" (10mm) Material: NdFeB Magnets + A3 Steel Plate Weight: 2.0lbs Accessories: 1*Eyebolt, 1*Bottle of thread locker, 1* Gasket, 1* Screw, 1* Drawstring bag How To Test The Pull Force The forces have been determined at room temperature on a plate of polished steel (A36) with a thickness of 1/2 inch. The pull force is applied perpendicular to the face of the plate. A maximum deviation of -10% compared to the specified force is possible in exceptional cases, generally the value is exceeded. Depending on the type of application (thickness/condition of base metal, temperatures, and direction of pull), the forces can be influenced enormously. Mounting on vertical surfaces can reduce the pulling force by up to 70%. The indicated values solely serve a basis for comparison under above stated conditions. Warning Children should not be allowed to handle or play with these magnets. This magnet is powerful and can accelerate at high speeds toward each other and toward ferrous material pinching skin. Keep away from children, pacemakers and electronics.
