Review: قوة قوية
Review: First, these are INSANELY strong magnets. I used them for a physics demonstration, and one of my students was not careful to empty their pockets before handling the magnet and it wiped the magnetic strip on his student I.D. in an instant. They will wreck havoc on your cellphone or computer. Not a toy by any stretch. These magnets are very difficult to separate, even if you are strong, and if they are anywhere near each other, they will come together so violently that they will chip or shatter each other. TAKE CARE! There is very little that you can do to keep these from smashing together once they are less than 5" away from each other. It hurts real pain to get your fingers involved between these. The little plastic spacer provided is not sufficient. I keep mine separated by a 1/2" thick piece of wood, and I can just barely get them apart that way when I want to use them. These are a great value though, super strong, and they perform better than I expected. Hours of fun with steel ball bearings or ferrofluid, and great for all kinds of demonstrations on magnetism.

## 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.
