Product Details
Made up of N52 neodymium magnet embedded a steel shell, it concentrates the magnetic field on the bottom and top of magnet which increase the magnetic force by 2.5-4 times compared to the naked magnet . The steel cup will prevent the naked magnet from cracking and chippings. Note: 1.The 1240LBS is the vertical magnetic pull-force which makes the magnet pull way from the 1.18"thickness steel plate of a tensile tester under ideal condition. It does not mean the actual weight which the fishing magnet can lift The actual pull force will vary mainly depending on the following variables: A: Steel thickness (The thicker the steel is, the stronger the pull force) B: Attracting position (The farther beyond the center of gravity of the attracted object, the lower the pull force). C: Pulling direction (The smaller the angle taking 90° as a standard, the stronger the pull force), the Pull force in horizontal direction is only about one third of that in vertical direction)
