Customer customization instructions
Magnet is a rare product, it is strongly recommended to read the product description and magnet common sense
The unit of Ndfeb magnet is mm (mm), so you should see the specific size when you buy, please do not buy by imagination, in order to avoid the wrong product.
(2) NdFeb magnets are fragile, especially thin slices and long strips. Please pay attention to operation. When separating the magnets, just like a sliding cover phone, it should be moved and staggered.it should not be broken directly.
(III) The surface of Ndfeb is protected by coating, which has anti-rust and anti-corrosion effect. If not used in time, please keep in a dry environment.
Ndfeb is very magnetic, so please stay away from your related electronic products, such as magnetic card, mobile phone, watch and so on.
(v) Keep strong magnets out of reach of children to avoid swallowing or clipping. Magnets should not collide to avoid injury caused by debris.
If it is to be made to order, please send us the drawings.

                             Warm prompt
(1) Nd-Fe-B strong magnetic material is hard, brittle, strong magnetic field, to take light (especially large size and thin sheet), when the strong magnet itself or other iron phase absorption or separation, careful operation should not impact, otherwise it is easy to cause collision and damage to the magnet or injured fingers.
(2) when the magnets can not be pulled apart from each other, it is recommended to push stagger, must not hard pry.
(3) Strong magnets should be away from iron and easily magnetized items, such as monitors, bank CARDS, computers, televisions, mobile phones, etc.
(4) Strong magnets should be stored in a dry and constant temperature environment, separated and wrapped with plastic, wood chips, cardboard, foam, etc.
(5) the object may have water meter, electric meter, gas meter and other measuring equipment is affected, the measurement is not accurate, so there may be some illegal events occur, for example: meters around make it slower, less pay for events, such as the country suffered losses, are illegal ACTS, such as my company is not liable.

                             Taking notes
For magnets with good magnetism and strong attraction, fix the whole magnet with your left hand, and use your right hand with your index finger and thumb to move the magnet horizontally. After moving out, do not immediately throw the removed magnet back into the magnet pile, please immediately isolate the magnet.
Place it lightly, away from the iron or magnetic objects (16 cm or so) or wrap the magnet in a piece of paper to make it thicker and safer. If you need to put the magnet back inside the whole magnet, please put it back slowly and move in close from the edge. The hand must hold the magnet until the magnet has moved in.

                           Parameters that
1 Magnetic field strength
The strength of the magnetic field depends on the grade and size of the magnet. It is wrong to think simply that the higher the brand grade is, the higher the surface magnetic field will be. The premise is the same specifications, the higher the brand, the higher the surface magnetic field! For example, N35 D3*10 has a magnetic surface greater than N50 D30*2
(2) Suction
The higher the surface magnetism, the greater the suction per unit area! Suction = magnetic per unit surface * per unit area. Therefore, we can not simply think that the magnetic high magnet suction must be large! For example, N50 D3*10 has less suction than N33 D10*5 (although N50 D3*10 has a larger surface magnetic field than N33 D10*5).
(3) Grade
Sintered NdFeb has a series of grades based on coerce (which determines temperature) and magnetic energy product (which determines the size of unit magnetic force). As an ordinary consumer, he only needs to master two factors (temperature and magnetic energy product).
The highest operating temperature of N gear is 80 degrees         The highest operating temperature of M range is 100 degrees
The highest operating temperature of H range is 120 degrees         The highest operating temperature of SH is 150 ℃
The highest operating temperature of UH station is 180 degrees       The highest operating temperature of EH gear is 200 degrees
The highest operating temperature of AH gear is 220 ° C
The Numbers in front of the letters represent the magnetic energy product, such as 45H, which tells us that the material has a maximum operating temperature of 120 degrees and a magnetic energy product of 45MGsOe (a unit name).
