Product Overview

Neodymium magnets are the world's strongest commercially available permanent magnets. Super Magnet Store offers premium-quality N45 neodymium magnets manufactured to stringent quality standards using advanced production technology. These magnets provide exceptional magnetic strength, dependable performance, and long-term durability for commercial, industrial, and engineering applications.

This N45 neodymium bar magnet measures 1.5" x 1/2" x 1/16" and generates over 7 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.

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

What Is a Neodymium Bar Magnet?

A neodymium bar magnet is a rectangular rare earth permanent magnet made from neodymium, iron, and boron (NdFeB). Bar magnets provide strong holding force and a large contact surface area while maintaining a compact profile, making them ideal for electronics, fixtures, displays, engineering projects, automation systems, and custom magnetic assemblies.

How Strong Is This Magnet?

This N45 neodymium bar magnet generates over 7 lbs of pull force under ideal conditions. Actual holding strength depends on steel thickness, surface finish, air gaps, alignment, and mounting configuration. With a Br Max rating of 13,800 Gauss, it delivers excellent magnetic performance in a thin-profile design.

Common Questions About This Magnet

How much weight can this magnet hold?

This magnet provides over 7 lbs of pull force under ideal conditions. Actual holding capacity depends on surface material, air gaps, alignment, 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 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 1.5" x 0.5" surfaces.
