Super Magnet Store offers premium-quality N42 neodymium magnets manufactured to stringent quality standards using advanced production technology. These magnets provide exceptional magnetic strength, dependable performance, and long-term durability for industrial, commercial, and engineering applications.
This N42 neodymium block magnet measures 2" x 1" x 3/8" and generates over 59 lbs of pull force under ideal conditions. Manufactured from neodymium, iron, boron, and other minor elements, it delivers significantly greater magnetic performance than N40, N38, and N35 grades.
The advanced Epoxy + Copper + Nickel triple-layer coating provides exceptional corrosion resistance, superior adhesion characteristics, and improved durability compared to standard epoxy-only coatings. It is particularly well suited for bonding applications, humid environments, and situations where enhanced chip and crack resistance is important.
What Is a Neodymium Block Magnet?
A neodymium block magnet is a rectangular rare earth permanent magnet made from neodymium, iron, and boron (NdFeB). Block magnets provide exceptional holding force and a large contact surface area, making them ideal for industrial equipment, manufacturing fixtures, automation systems, engineering projects, magnetic assemblies, and custom applications.
How Strong Is This Magnet?
This N42 neodymium block magnet generates over 59 lbs of pull force under ideal conditions. Actual holding strength depends on steel thickness, surface finish, air gaps, temperature, and mounting configuration. With a Br Max rating of 13,200 Gauss, it delivers powerful magnetic performance for demanding industrial applications.

Common Questions About This Magnet
How much weight can this magnet hold?
This magnet provides over 59 lbs of pull force under ideal conditions. Actual holding capacity depends on surface material, air gaps, steel thickness, and application design.
Why choose the Epoxy + Copper + Nickel coating?
This coating offers superior corrosion resistance, improved adhesion to metal surfaces, and greater resistance to cracking and chipping compared to standard epoxy-only coatings.
Is N42 stronger than N35?
Yes. N42 magnets provide substantially greater magnetic energy and holding force than N35 magnets of the same dimensions.
Can this magnet be used outdoors?
Yes. The Epoxy + Copper + Nickel coating provides enhanced protection against moisture and corrosion, making it better suited for outdoor and humid environments than standard nickel-coated magnets.
What direction is it magnetized?
This magnet is magnetized through the 3/8-inch thickness, with the north and south poles located on the 2" x 1" flat surfaces.
