This is a ultra tiny ring small flat magnet, is made of rare earth neodymium and has a strong powerful. The specific size is 3.5mm in outer diameter, 1.2mm inner diameter and 1.4mm thickness. Our company can generally achieve the minimum specification of the magnetic ring is D3 x 1 x 1(1/8" x 1/16" x 1/16" inchs). The sample is plated zinc and is light blue. The price of zinc plated is lower than nickel plated, but the luster and performance will be worse than the effect of nickel plated. It can working at 120℃ temperature(up to 220ºC for neodymium magnet)
The magnetizing direction is thickness and center surface strength is about 1940Gs. The single weight is 0.089g. We must take care when we pick up one magnet. One reason is one magnet of this sample is more than light, the second reason is magnet is very brittle and more prone to breakage, the last one is the tiny magnets always has strong power in magnetism, small size neodymium magnets may pinch fingers, and medium to large size neodymium magnets may injure hands or fingers!
Correct split form:
1.Use the thumb to move the top magnet away long distance, avoid adsorption and collision, and cause fragmentation
2.When two magnets are needed to suck, avoid the collision and crushing of the air suction, both hands should grasp a magnet from the edge slowly at the same time , and be carefully
The application of Mini Neodymium Ring Magnet D3.5x1.2x1.4mm:
We do not advice the children's toy(Especially for those who have no sense of safety) use mini neodymium magnet unless it is very necessary!
It can be widely used in craft, models, bjd doll, refrigerator magnets, precision instruments, miniature cameras, hardware products, magnetic repulsion, magnetic suspension and so on
