Black nickel-coated Neodymium disc magnet has a pull force of 0.2540kg, with a weight of 2 grams, a height of 1.58mm and a diameter of 3.18mm. Gauss5232, GradeN52 and direction of magnetisation through height.

These Neodymium discs may be tiny, but their small size is compensated for with a high-grade N52 magnetic material, and that’s a match made in heaven. It means these tiny disc magnets can occupy a smaller physical space while maintaining high magnetic effectiveness, important in any industry where size and weight reduction matters. By delivering improvements in performance, these Rare Earth magnets can help to reduce production costs and that bottom line is increasingly important as cost burdens increase. Neodymium magnets are used in almost every technological innovation, in industries such as robotics, aerospace, communications, automotive and the military.

Small disc magnets are often found in sensory devices and alarm systems where they provide reliable information and perform accurate duties continually, with little or no maintenance requirements.

This magnet stands out in our range because of its black nickel coating, which although it doesn’t change its performance, does have added appeal in some applications where a more reflective coating may have an impact on other functions.


Small sized Neodymium discs like this can have their reduced magnetic power output, due to size, compensated for by using high-grade N52 magnetic material. This means they can occupy a smaller physical space while maintaining high magnetic effectiveness. This is important in any industry where size and weight reduction is important in achieving improvements in performance and helps to reduce production costs. Today this includes nearly all areas of technological innovation and covers industries such as Robotics, Aerospace, Communications, Automotive and the Military. Small discs are often found in sensory devices and alarm systems where they provide reliable information and perform accurate duties continually with little or no maintenance requirements. The Black Nickel coating on this product provides little additional benefit to its performance but may have appeal in some applications where a more reflective coating causes problems.

WARNING!: ALL MAGNETIC PRODUCTS ARE A POTENTIAL SWALLOW HAZARD FOR CHILDREN AND VIGILANT PARENTAL SUPERVISION IS REQUIRED AT ALL TIMES.
