2/5/10/15/20/50PCS 20×3-5 Countersunk Round Search Magnet 20*3 With Hole 5mm Disc Permanent Neodymium Magnet 20×3-5mm 20*3-5
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. .
