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.

Description:

      D4x2mm Neodymium Magnets N50 are some of the strongest magnets available today. With their small size and impressive holding strength, these magnets are ideal for a wide range of applications. These n50 4x2mm magnets are made from neodymium, a rare earth element that creates a powerful magnetic field. Measuring just 4mm x 2mm, they can hold up to 1.5kg of weight, making them perfect for use in electronics, model making, and even jewelry. These n50 4x2mm magnets are also great for use in science experiments and educational projects. They can be used to teach students about magnetism, or to demonstrate how magnets work. With their incredible strength and versatility, these 4x2mm magnets are an essential component for anyone who wants to create something innovative and unique. So if you’re looking for a reliable and powerful magnet, look no further than these n50 4x2mm magnets.
