The composition of the magnet is atoms such as iron, cobalt, and nickel. The internal structure of these atoms is quite special and has a magnetic moment. Magnets can generate magnetic fields and have the property of attracting ferromagnetic materials such as iron, nickel, cobalt, and other metals.
The material of neodymium iron boron magnet is particularly fragile (it is also called a powerful magnet). Therefore, be careful when using powerful magnets and avoid collisions. If they fall on the ground, they can easily be broken.
For magnets that are attracted together, if you pull them hard, it is easy to pinch your hands and the magnets may be damaged. Please try to use push and pull to separate them, you can use parallel force to push them apart. For large-sized magnets, try to require magnet manufacturers to use environmentally friendly paper pads to separate them, so as not to use a lot of effort and easy to get injured.
If it is a bar magnet, it must be placed in pairs, and the N pole of the A magnet is close to the S pole of the B magnet to prevent demagnetization.
