## Features

- Composition - Neodymium magnets are composed of neodymium (Nd), iron (Fe), and boron (B). The combination of these elements results in a crystalline structure that contributes to the high magnetic properties. However, this crystalline structure also makes the magnets less hard than other carbon steels.
- Feature - Various sizes can satisfy your various choices. We provide the perfect size for a variety of applications. These magnets have a triple layer coated with Nickel+Copper+Nickel to provide shiny and durable protection.
- Applications - These magnets are used for educational, research, professional, commercial, or industrial purposes that are sold or distributed to school educators, researchers, professionals, or commercial or industrial users.
- Tips- Magnets can attract to each other with great force, so avoid dropping them or subjecting them to impacts.
- Service - Search for Realth on desertcart for more sizes, shapes, functions, and other unique magnets. Our products are designed based on actual demands and needs and are made under ISO 9001 Quality Systems. Please contact desertcart customer service for the after-sale service.

## Questions & Answers

**Q: Why do neodymium magnets break easily?**
A: The Neodymium magnets that you use are not actually made from solid chunks of metal, but are rather made by compressing a large amount of powder into blocks through a process called sintering. This is the reason they are so brittle.

**Q: What do I need to pay attention to in the use of neodymium magnets?**
A: Neodymium magnets are not children's toys. Keep the neodymium magnet at least 25 centimeters away from electronic devices. Keep the neodymium magnet at a very safe and long distance from people with pacemakers or implantable cardiac defibrillators.

**Q: What grades of neodymium magnets are usually available?**
A: In general, neodymium magnets are available in grades ranging from N35 to N55. The higher the grade or N number, the stronger the magnetism.

**Q: How to separate two magnets correctly?**
A: The Edge Technique Utilize the edge of table or desk by positioning the magnets where they are joined and then carefully pushing the magnets apart. Be sure to quickly separate the magnets and store far enough away from each other.

### ⭐⭐⭐⭐⭐ SUPER Strong Mangnets
*by S***Y on January 11, 2025*

Watch out, these slam together HARD and could give you a serious pinch.They easily break if you allow them to slam together, don't do that!!

### ⭐⭐⭐⭐⭐ Extremely powerful magnets
*by S***N on May 27, 2025*

These worked perfectly for what I needed it for!! Extremely strong for size!!!

### ⭐⭐⭐⭐ Very Strong and Delicate
*by R***Y on February 21, 2024*

These magnets are very strong and do a great job at holding however be careful letting them attach to one another too quickly as this often breaks magnets, I have already lost 5 of 20 ordered. There are other versions of this magnet with backing or protection that may better suit your need.
