Product Description

This versatile N52 neodymium magnet block combines strong magnetic performance with a practical rectangular design. Made from premium rare earth alloy of neodymium, iron, and boron, it delivers reliable 9.4 lb pull force in a compact, low-profile form factor.

The magnet features protective nickel-copper-nickel coating to prevent corrosion and ensure long-term durability. Despite its powerful magnetic strength, the brittle ceramic-like construction requires careful handling to prevent damage from impact or collision.
