Magnet with Centre Hole – 4.74 mm Diameter

Tiny magnet (4.74 diameter x 1.57 mm thick) made of Neodymium / Iron / Boron (NdFeB)

SKU 7300-MAGNETRINGEAN 8219671018951Item type: Magnet

Description

The tiny Neodymium/Iron/Boron (NdFeB) magnet is a concentration of magnetic power in an incredibly compact format. With a diameter of just 4.74 mm, a thickness of 1.57 mm, and a central hole of 1.5 mm, this magnet is perfect for a wide range of applications.

Made from high-quality materials, the Neodymium/Iron/Boron magnet offers excellent magnetic strength. Its N42 grade magnetization ensures superior performance, allowing you to make the most of the magnet in various contexts.

The central hole allows for secure attachment to the surface on which it is applied. You can use a screw or pin to fix it easily, ensuring reliable hold in any situation.

Weighing only 0.189 g, this magnet is extremely light, but don’t be fooled by its small size. Its pull force of 1.48 lbs allows you to use it in multiple applications, offering powerful and reliable holding.

Thanks to the nickel plating (Ni-Cu-Ni), the magnet is protected from corrosion and has a pleasant aesthetic appearance. Furthermore, the axial magnetization direction promotes a coherent magnetic flux and optimizes performance.

With a magnetic field surface of 2275 Gauss, a Brmax value of 13,200 Gauss, and a BHmax of 42 MGOe, this Neodymium/Iron/Boron (NdFeB) magnet stands out for its magnetic power and superior technical characteristics.
