Safety Warning
Neodymium magnets are brittle, super strong, easily shattered and broken, Here are some tips that will help when working with neodymium magnets: |
1. Wear eye protection and gloves when working with magnets if necessary. |
2. Slide the magnets rather than pulling off the stack. |
3. Keep away magnets from kids in case accident happens. |
4. Keep away magnets from objects that might cause damage like smartphone, GPS, pacemaker or other electronic devices. |
5. Do not put magnets in high temperature environment, magnets will demagnetize while they are over heated. |
6. Magnets can rust and get scratched because magnets contain iron and mostly are nickel plated. |

D5x4mm Neodymium Magnets N42 are small but mighty magnets that pack a powerful punch. These round magnets, measuring 5mm in diameter and 4mm in thickness, are made of rare earth materials and are known for their incredibly strong magnetic force. With a grade of N42, these magnets are some of the strongest available, making them perfect for a variety of applications where a small, yet strong, magnet is needed.
These small but powerful magnets are commonly used in crafts, DIY projects, and industrial applications. Their compact size makes them a popular choice for use in electronics, such as speakers, motors, and sensors. They are also ideal for use in jewelry making, magnetic clasps, and other decorative applications. The strong magnetic force of these 5mm round magnets allows them to securely hold even heavy objects in place.
