Super Magnet Store offers premium-quality N45 neodymium magnets manufactured to stringent quality standards using advanced production technology. These magnets provide exceptional magnetic performance, reliable strength, and long-term durability for industrial, commercial, and engineering applications.

This N45 neodymium block magnet measures 1" x 1/4" x 1/16" and generates approximately 4.5 lbs of pull force under ideal conditions. Manufactured from neodymium, iron, boron, and other minor elements, it delivers stronger magnetic performance than N42, N40, N38, and N35 grades while maintaining a slim profile suitable for compact applications.

The durable Nickel-Copper-Nickel triple-layer coating provides enhanced protection against corrosion and wear. Manufactured under ISO-certified quality standards, this magnet offers consistent magnetic performance and dependable reliability in demanding environments.

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 magnetic strength and a large contact surface area, making them ideal for manufacturing, electronics, engineering projects, automation equipment, and custom magnetic assemblies.

How Strong Is This Magnet?

This N45 neodymium block magnet generates approximately 4.5 lbs of pull force under ideal conditions. Actual holding strength depends on steel thickness, surface finish, air gaps, temperature, and mounting configuration. With a BrMax rating of 13,500 Gauss, it delivers strong magnetic performance despite its thin profile.

Common Questions About This Magnet

How much weight can this magnet hold?

This magnet provides approximately 4.5 lbs of pull force under ideal conditions. Actual holding capacity depends on the mounting surface and application design.

Is N45 stronger than N42?

Yes. N45 magnets provide greater magnetic energy and holding force than N42 magnets of the same dimensions.

Can this magnet be used outdoors?

The Nickel-Copper-Nickel coating provides good corrosion resistance, but additional protection is recommended for prolonged outdoor exposure.

Can it rust?

The protective nickel coating helps resist corrosion; however, moisture exposure and coating damage can eventually result in rust.

What direction is it magnetized?

This magnet is magnetized through the 1/16-inch thickness, with the north and south poles located on the 1" x 1/4" flat surfaces.
