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. |

D3x4mm Neodymium Magnets N42 are small but mighty magnets that can hold up to 0.179 kg/0.395 lbs of weight. These 3mm round magnets are made of neodymium, one of the strongest magnetic materials available. Their small size makes them perfect for use in tight spaces where a larger magnet won’t fit. Use them in DIY projects, arts and crafts, or as a fastener for small items. These small round powerful magnets are perfect for holding notes, photos, or other small items on a fridge or magnetic board. The 3mm neodymium magnets can also be used in magnetic therapy, or as a component in electronic devices. With a nickel-plated finish, these magnets are corrosion-resistant and can withstand high temperatures. Get your hands on these small yet powerful magnets today and discover all the ways you can use them in your projects!
