Product Description

N42 Neodymium Block Magnet 1/2" x 1/4" x 1/8" Rare Earth Bar Magnet

Engineered for high performance and reliable holding power, this N42 Neodymium Block Magnet measures 1/2 inch in length, 1/4 inch in width, and 1/8 inch in thickness. Made from high-grade NdFeB (Neodymium Iron Boron) alloy, this rectangular bar magnet delivers strong magnetic strength in a compact profile, making it ideal for industrial, commercial, and precision DIY applications.

Key Features & Specifications

  • Dimensions: 1/2" L x 1/4" W x 1/8" T (0.500" x 0.250" x 0.125" / 12.7mm x 6.35mm x 3.175mm)
  • Magnetic Grade: Grade N42 Rare Earth NdFeB
  • Residual Flux Density (Br): 13,000 – 13,200 Gauss (1.30 – 1.32 Tesla)
  • Surface Field: ~4,170 Gauss
  • Pull Force: Approx. 4.8 lbs (2.18 kg) direct attraction to steel plate
  • Magnetization Direction: Axially magnetized through the thickness (0.125"), poles on the 1/2" x 1/4" surfaces
  • Coating: Ni+Cu+Ni (Nickel-Copper-Nickel) 3-layer premium protective plating for corrosion resistance
  • Tolerance: Precision manufactured within +/- 0.002" (+/- 0.05mm)
  • Operating Temperature: Max 176°F (80°C)

Versatile Applications

This compact N42 bar magnet offers an exceptional balance of strength and small footprint. Common uses include:

  • Precision magnetic assemblies, latches, and sensors
  • DIY woodworking, cabinetry, and invisible magnetic closures
  • Model making, scale engineering, and robotics projects
  • Retail displays, signage mounting, and trade show fixtures
  • Tool organization, science fair projects, and educational labs

Safety Warning: Neodymium magnets are powerful and brittle. Handle with care to prevent chipping or pinching injuries. Keep away from pacemakers, electronic devices, and children.

Warranty

This magnet includes a 10-year warranty for its magnetic strength, provided it is used under normal conditions. Usage in environments with elevated temperatures, significant vibration, or intense opposing magnetic fields will render this warranty null and void. It is also not suitable for use outdoors or in areas with high humidity or salt content, unless additional protective insulation measures are implemented.
