Realth Neodymium Magnets Disc, Thick Disc Magnet, Rare Earth Magnetic for Research Industrial Purposes Educational (MC301): desertcart.com: Industrial & Scientific

Review: WOW!!!!!!!! Now THIS is a strong magnet! Crackling under my skin heard!! - I am using this for magnet therapy and moving/removing certain heavy metals- sounds crazy but I hear stuff moving. The only thing is DON'T let the two get stuck together it is super hard getting them apart! I know, my therapeutics are odd, but I can tell you that for magnet therapy these work. For storage I put them on either side of cardboard so I have a way to slide one off to use. I have a small sticker on the top of each so I can tell how to not place them. Very good purchase for the money. Do NOT let this next to your computer, credit cards, etc!!! Have fun.
Review: Strong, but not for erasing magnetic tapes. - Nothing against the strength of these magnets; they’re very powerful. However, I bought them hoping to use them for erasing miniDV tapes. Regrettably, they only erase them in spots, despite my best efforts. They are very powerful, however, and would probably excel at other tasks.

## 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.
- High Temperature Resistant: Our magnets have excellent high-temperature resistance, can maintain a stable working condition in high-temperature environments, and are not easy to be deformed and demagnetized, ensuring long-term stable adsorption effect.

## 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.
