2/5/10/15/20PCS 20×8 round search magnet 20mm X 8mm rare earth neodymium magnet disk 20x8mm strong permanent magnet 20*8 mm

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 magnet product is N35. Please purchase the corresponding grade of magnet according to the actual application needs.
2. NdFeB magnets should be stored in a ventilated and dry room. Acids, alkalis, organic solvents, water, and high temperature and high humidity environments are likely to cause magnets to rust, coatings to fall off, magnets to pulverize, and demagnetize.
3. The magnet should be kept away from magnetically sensitive objects such as disks, magnetic cards, tapes, bank cards, watches, and electronic medical devices such as cardiac pacemakers.
4. The magnet material is hard and brittle. It is made of sintered powder. During use, it should be ensured that the magnet will not be severely impacted. Please, handle with care. If it is used improperly, it is easy to cause damage and cracking of the magnet, which has nothing to do with the quality of the magnet.
5. The larger and thicker the magnet, the stronger the magnetic force. Please prevent your fingers from being hurt by magnets during use. .
6. It is forbidden to use under the age of 14.
7. If you have any questions, please leave us a message, we will deal with it for you in the first time, and keep friendly communication.
8. After placing an order, you can check the tracking information through the link or https://global.cainiao.com.
