Excellent Material & Quality: Neodymium NdFeB (neodymium-iron-boron) magnet with maximum N52 magnetization! These so-called "rare earth magnets" are truly extremely powerful, precisely because of their very high magnetizing power. Both powerful neodymium magnets and super strong magnets find their place in the kitchen as refrigerator magnets, in model making, assembly, on magnetic boards, and throughout the home, for hobbies, and in the office. Supply: You will receive 10 tubular neodymium magnets (rod magnets/magnetic rods/cylindrical magnets/powerful rod-shaped magnets) measuring 4 x 10 mm (diameter x height). Cylindrical magnets are axially magnetized along their entire thickness, i.e., their height. This means that the north pole & The magnetic south poles are located on the large surfaces of the rod magnets. Exceptional coating: The magnets are triple-coated with a nickel-copper-nickel (NiCuNi) coating, giving them a smooth, bright silver surface capable of withstanding strong stresses and, even if only partially, external agents (such as corrosion)! However, it should be remembered that these magnets are not indestructible and should therefore be used with care. If they collide violently, the alloy may be damaged. Versatile applications: The N52 magnetization guarantees a particularly strong magnetic attraction. It is even possible to attach multiple layers of photos, postcards, business cards, various tickets, calendars, household diaries, newspaper articles, paper clips to refrigerators, whiteboards, magnetic boards, magnetic panels, wall-mounted magnetic panels, magnetic bars, whiteboards & other metallic surfaces (e.g., iron, steel, sheet metal). Neodymium magnets are characterized by a particularly high attractive force and, as such, are not toys!
