## 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.
