Product Description

This 3" x 0.25" N42 neodymium disc magnet is designed for applications that need a larger magnetic surface and reliable holding performance in a compact round shape. Its 3-inch diameter provides a broad contact area, while the quarter-inch thickness adds additional magnetic depth, making it a practical option for mounting systems, fixtures, equipment, displays, and custom projects. Manufactured from neodymium, iron, and boron, this NdFeB rare earth magnet uses N42 grade material to provide stronger magnetic performance than N40, N38, and N35 grades. With a BrMax rating of 13,200 gauss, it offers consistent magnetic performance for applications where dependable holding power is important.

The magnet is magnetized through its thickness, with the magnetic poles located on the two flat surfaces. This orientation creates a direct and predictable magnetic connection, allowing the disc to work well in designs that rely on full-face magnetic contact. A Nickel-Copper-Nickel triple-layer coating helps protect the magnet from corrosion, moisture, and everyday wear. This durable finish helps maintain the magnet’s surface quality and supports reliable performance over extended use.

Built with carefully controlled manufacturing standards, this N42 neodymium disc magnet provides a practical balance of size, durability, and dependable magnetic performance for industrial, commercial, and custom applications.

Approximate pull force: over 73 lbs
