Product Description

This magnet is a high-quality neodymium magnet, featuring a diameter of 18 mm and a height of 3 mm, with precise tolerances of ±0.1 mm. With a weight of approximately 5.7 grams, it offers a powerful magnetic pull capable of holding up to about 3.2 kilograms.

The magnetization direction is along its 3 mm dimension, ensuring strong magnetic performance. It is coated with layers of nickel, copper, and nickel (Ni + Cu + Ni), providing excellent corrosion resistance and durability. This coating enhances the magnet's longevity and protects it from environmental factors.

Manufactured from N38 grade neodymium material, this magnet boasts impressive magnetic properties. It exhibits high coercivity (Hcb) and coercivity intrinsic (HcJ) values, ensuring reliable magnetic performance. Additionally, it features a remanence (Br) of 1.22-1.25 Tesla and an energy density (BH) max of 287-310 kJ/m3.

With a maximum temperature resistance of 80°C, this magnet is suitable for various applications, including industrial, commercial, and hobbyist uses. Whether you're securing objects in place, organizing tools, or experimenting with magnetic properties, this magnet offers superior strength and versatility.

Frequently asked questions (FAQ):

1. What are neodymium magnets used for?

  • Neodymium magnets are widely used in various applications such as magnetic closures, magnetic therapy, sensors, motors, generators, magnetic levitation systems, and more.

2. How strong are neodymium magnets?

  • Neodymium magnets are among the strongest permanent magnets available commercially. Their strength is measured in terms of their magnetic energy product (BHmax), which ranges from around 33 to 52 megagauss-oersteds (MGOe) for standard grades.

3. Are neodymium magnets safe to handle?

  • While neodymium magnets are safe for general handling, they are extremely strong and can cause injuries if not handled with care. It's important to keep them away from electronic devices, credit cards, and pacemakers, as they can cause damage.

4. How do I store neodymium magnets?

  • Neodymium magnets should be stored away from magnetic-sensitive items and kept in a cool, dry place to prevent corrosion. When storing multiple magnets, it's advisable to separate them with non-magnetic materials to avoid unintended attraction.

5. Can neodymium magnets be recycled?

  • Yes, neodymium magnets are recyclable. Since they contain rare earth elements, recycling them helps reduce the need for mining new resources. Many recycling centers accept neodymium magnets, or you can repurpose them for other projects.
