Product Overview
Neodymium magnets are the world's strongest commercially available permanent magnets. Super Magnet Store offers premium-quality N52 neodymium block magnets manufactured to stringent quality standards using advanced production technology. These magnets deliver exceptional magnetic strength, reliable performance, and long-term durability for industrial, commercial, and engineering applications.
This N52 neodymium block magnet measures 3" x 1/2" x 1/2" and generates over 75 lbs of pull force under ideal conditions. Manufactured from neodymium, iron, boron, and other rare earth elements, it provides stronger magnetic performance than N50, N48, N45, N42, N40, N38, and N35 grades.
The Nickel-Copper-Nickel triple-layer coating provides outstanding corrosion resistance and surface durability, making it suitable for demanding work environments. Its long rectangular profile offers excellent contact area for magnetic holding, positioning, and structural applications.
What Is a Neodymium Block Magnet?
A neodymium block magnet is a rectangular permanent magnet manufactured from neodymium, iron, and boron (NdFeB). Block magnets provide exceptional holding force across a large contact surface while maintaining a compact profile, making them ideal for industrial machinery, automation systems, magnetic fixtures, robotics, woodworking, and engineering projects.
How Strong Is This Magnet?
This N52 neodymium block magnet produces over 75 lbs of pull force under ideal conditions. Actual holding strength depends on steel thickness, surface finish, air gaps, operating temperature, and mounting configuration. With a Br Max of 14,200 Gauss, it delivers maximum magnetic performance for heavy-duty industrial applications.

Frequently Asked Questions
How much weight can this magnet hold?
This magnet provides over 75 lbs of pull force under ideal conditions. Actual holding capacity depends on the steel surface, alignment, air gaps, and installation method.
Is N52 stronger than N50?
Yes. N52 provides greater magnetic energy and holding force than N50 and all lower commercial neodymium grades.
What direction is it magnetized?
The magnet is magnetized through the 1/2-inch thickness, with the north and south poles located on the 3" × 1/2" faces.
Can this magnet be used outdoors?
The Nickel-Copper-Nickel coating provides excellent corrosion resistance. For prolonged outdoor or marine exposure, additional sealing or a protective enclosure is recommended.
What is the maximum operating temperature?
This standard N52 magnet is designed for continuous operation up to 176°F (80°C). Exposure to higher temperatures may permanently reduce magnetic strength.
Do you offer wholesale pricing?
Yes. Contact Super Magnet Store for competitive wholesale pricing and volume discounts on N52 neodymium block magnets.
Safety Notice
Neodymium magnets are extremely powerful and can snap together with significant force, causing pinch injuries or chipping. Handle with care and keep away from children, pacemakers, sensitive electronics, and magnetic storage media. Always review magnet safety guidelines before use.
