10pcs/lot N52 Square Neodymium Magnets | Ultra-Strong Rare Earth Industrial Magnets

Harness the extreme power of the world’s strongest magnetic material with our 10pcs/lot N52 Square Strong Magnets. Engineered for high-performance applications, these neodymium magnets offer unparalleled pull force in a compact, square profile. Whether you are organizing a professional office, securing heavy items on refrigerators, or integrating them into handheld devices and DIY engineering projects, these N52-grade magnets provide a professional-grade solution. With a diameter/width range of 30-50mm, they are specifically designed for tasks that require maximum magnetic flux and stability. These are not your average craft magnets; they are high-energy industrial components that provide a secure, "locked-in" hold for any ferromagnetic surface.

Key Features

• Elite N52 Magnetic Grade: The highest commercial grade available, providing up to 50% more magnetic energy than standard N35 magnets.

• Heavy-Duty Square Profile: Specifically shaped for maximum surface contact, ensuring a stable and non-slip grip on flat surfaces.

• Triple-Layer Coating: Finished with a Ni-Cu-Ni (Nickel-Copper-Nickel) plating for superior corrosion resistance and a sleek, professional look.

• Multipurpose Utility: Ideal for refrigerators, whiteboards, magnetic tool racks, scientific experiments, and custom furniture latches.

• Compact & Powerful: Delivers incredible holding power without the bulk, perfect for space-sensitive handheld devices.

⚠️ Safety Warning N52 magnets are extremely powerful. They can pinch skin or cause injury if allowed to snap together unexpectedly. Keep away from pacemakers, electronic devices (laptops/phones), and credit cards. Keep out of reach of children.

Why Choose Our N52 Magnet Lot Unlike low-grade ceramic magnets that chip and lose strength, our strong N52 magnets are permanent rare-earth alloys that maintain their magnetism for decades. The precision-molded square edges provide a much more professional and "flush" look for your home or office compared to round disc magnets. They offer a high-value, "industrial-strength" aesthetic that ensures your projects stay exactly where you put them.
