## Features

- HIGH QUALITY: Made from strong neodymium-iron-boron alloy (NdFeB) and have a stylish nickel coating (Ni-Cu-Ni) with an appealing silver surface --- All the magnets are magnetized axially and have a maximal operating temperature of 80 degrees Celsius

- LARGE SIZE: Diameter 40mm x thickness 20mm(approx.1.57"x0.79" ).Tolerances: ±0.2mm x ±0.2mm. Stronger magnetic properties and wider applications than ordinary magnets
- USAGE TIPS: Neodymium magnets are not actually made of solid blocks of metal, but rather large amounts of powder pressed into blocks through a process called sintering. When subjected to a sudden impact, they will break. To prevent the magnets from breaking, the two magnets should be separated by a large distance to prevent them from being attracted and collided.
- PURCHASE TIPS: If you purchased it to remove, please buy a combination of 2. The combination of 2 pieces has stronger magnetism. One piece of magnetic block can only be used for 85% of the labels on the market, and two pieces combined can be used for 98% of the labels on the market

## Questions & Answers

**Q: Why are neodymium magnets so fragile?**
A: Neodymium magnets aren't actually made from solid blocks of metal, but rather from compacting large quantities of powder into blocks through a process called sintering. They tend to break easily when subjected to sudden impact.

**Q: Why should you be careful when using it?**
A: Its magnetic force is very strong, and your fingers may be caught between the two magnets accidentally, which may cause your fingers to be pinched, so children should be kept away from it.

**Q: How to separate two magnets correctly?**
A: Place two magnets on the edge of a table, push down on the outer magnet, and once they are separated, quickly move them far enough apart to prevent them from being attracted to each other again.

**Q: Why keep magnets away from electronic devices such as mobile phones?**
A: Magnets have strong magnetism and can interfere with electronic devices such as mobile phones and computers, causing data loss or damage.
