N45 Block 1/4 x 1/8 x 1/8 inch Magnets– Miniature Rare Earth Magnet for Compact Precision Applications

Experience the powerful performance of N45 neodymium magnets in a compact form factor designed for precision projects. Measuring just 0.25" x 0.125" x 0.125", this miniature block magnet delivers significant holding force relative to its size, making it ideal for electronics, sensor assemblies, hobby projects, and lightweight closures where space is at a premium.

Key Features:

  • Compact Mini Block Magnet: Small 0.25" x 0.125" x 0.125" size for tight spaces while providing stable, focused magnetic strength.
  • High-Strength N45 Grade: Stronger than N42, N40, N38, and N35, delivering a BrMax of 13,200 gauss for reliable magnetic performance.
  • Estimated Pull Force: Holds up to 2.4 lbs under ideal conditions (flat, clean steel). Actual holding force may be lower depending on surface and alignment.
  • Triple Coated: Nickel-Copper-Nickel plating ensures corrosion resistance and durability, extending lifespan in workshop or lab environments.
  • Magnetized Through Thickness: North and south poles are located on the 0.25" x 0.125" faces for consistent alignment in assemblies.
  • Brittle Material: Handle with care. These magnets are strong but can chip or break if dropped or allowed to collide with hard surfaces.
  • Max Operating Temperature: Rated for continuous use up to 80°C (176°F). Higher temperatures may permanently reduce magnetic strength.

Engineered for Precision Micro Applications

This N45 miniature neodymium block magnet is ideal for engineers, hobbyists, and educators who need maximum strength in the smallest possible package. Whether building models, aligning sensors, or prototyping compact assemblies, it offers a powerful, reliable magnetic hold while occupying minimal space.

Common Applications:

  • Magnetic positioning in robotics and micro-mechanical projects
  • Small sensor and switch activators
  • Magnetic closures for mini enclosures or jewelry boxes
  • Educational kits and science demonstrations
  • Holding lightweight tools or parts in compact fixtures
  • Prototyping in electronics and PCB applications

Frequently Asked Questions

How strong is this small N45 magnet?
Despite its compact size, this N45 magnet can hold up to 2.4 lbs under ideal conditions, making it ideal for lightweight positioning and closures requiring secure hold in small spaces.

What coating does it have?
It features a Nickel-Copper-Nickel triple-layer coating for corrosion resistance and durability in various environments.

Can this magnet be used in electronic projects?
Yes, its compact size and strength make it excellent for PCB positioning, sensor triggers, and other electronics requiring micro magnetic solutions.

What is the maximum temperature this magnet can safely handle?
N45 magnets can be safely used up to 80°C (176°F). Higher temperatures may permanently reduce magnetic strength.

What precautions should I take when using small neodymium magnets?
They can snap together with force, risking pinched fingers or damage to the magnet. Handle carefully, keep away from electronics and pacemakers, and avoid letting them collide during handling.

Safety Note:

Neodymium magnets are extremely strong for their size and can snap together unexpectedly, risking pinched fingers or chipping. Always handle carefully, keep away from children and sensitive electronics, and follow safety guidelines when using them in projects.
