Notes:
1.The grades of powerful magnets usually include N30, N35, N38, N40, N45, N50, N52, etc. the higher the magnet grade, the greater the magnetic force. The grade of our store magnet products is N35. Please buy the corresponding grade magnets according to the actual application needs.
2. Nd-Fe-B magnets are suitable to be stored in a ventilated and dry room. The environment of acid, alkaline, organic solvent, water, high temperature and humidity is easy to cause the magnets to rust, the coating to fall off, and the magnets to be powdered and demagnetized.
3. The magnet should be kept away from magnetic sensitive objects such as disk, magnetic card, tape, bank card and watch, as well as electronic medical devices such as pacemaker.
4. The magnet material is hard and brittle. It is made of sintered powder. In the process of use, it should be ensured that the magnet will not be severely impacted. Please handle it with care. If it is used improperly, it is easy to cause the magnet to be damaged and cracked, not the quality of the magnet.
5. The bigger and thicker the magnet is, the stronger the magnetic force is. Please prevent your fingers from being hurt by the magnet during use. .
6.It is forbidden for people under 14 years old to use it.
7.If you have any questions, please leave a message to us and we will deal with them for you at the first time to maintain friendly communication.

Application：
Sintered NdFeB permanent magnet materials have excellent magnetic properties and are widely used in electronics, electric machinery, medical devices, toys, packaging, hardware machinery, aerospace and other fields. The more common are permanent magnet motors, speakers, magnetic separators, computer disk drives, magnetic resonance imaging equipment and instruments, etc。

NOTICES
1. The NdFeB magnet is sold by size, the unit of measurement is millimetre, please pay attention to the size.
2. Related electronic products, such as Mechanical watchs ,bank cards, mobile phones, computers, televisions, pacemakers, etc., they are easily affected by neodymium magnets, please keep a certain distance to avoid unnecessary losses.
3. When connecting two magnets, draw them close to each other slowly and gently.  Hard crushing would cause damage and cracks in the magnetic material ,The NdFeB magnet have unbelievable magnetic performances , Don't hurt your hands when in use
4. The neodymium magnets are fragile, especially for the large-sized strips and sheets,Please put them lightly , and be careful to stagger the magnets when separating.
5.Please keep away the magnet from high temperature and corrosive environment，although there is a coating on the surface of the magnet.
6. If you have any questions, please keep good communication with us.

NOTICES
1. The NdFeB magnet is sold by size, the unit of measurement is millimetre, please pay attention to the size.
2. The magnetic property is very strong and the hand is pinched carefully. It is fragile and can be dried and stored at room temperature; 3. The magnet is made of powder powder sintering, which leads to the fragility of physical properties, which is not a quality problem;
4. Only iron can conduct magnetism, and the metal without iron can not be adsorbed；
5.Please do not contact with water. It is easy to rust in humid and corrosive environment；
