Product Features Introduction

Material and magnetic source:

Neodymium magnet (NdFeB) is a rare earth permanent magnet material composed of neodymium, iron, and boron, which has extremely high magnetic properties and is currently the strongest permanent magnet in terms of magnetism. Its magnetic grade is usually represented by "N" plus a number (such as N35, N52), the larger the number, and the stronger the magnetism.

Magnet coating:

The nickel plating magnets consists of three thin and uniform layers of Ni+Cu+Ni protective coating, designed to prevent oxidation and corrosion. It enhances the durability of the magnet while providing a smooth and aesthetically pleasing surface.

How to separate magnets:

When you need to use these block strong magnetic magnetsexercise caution by sliding them apart to separate them, keep them away from children, electronic devices, and items that are susceptible to magnetic fields, and ensure safe operation.

Usage:

The magnet will not leave any marks or stains when removed from a metal surface. Bar magnets are suitable for various applications, including refrigerator magnets, push pins, whiteboard magnets, photo displays, tool storage, and scientific experiments.
