One-sided magnets and magnet which some difference
At present there are magnetic, if you need to use the single side are on one side of the magnetic don't add a iron magnetic shielding cover to keep out, there is no real single magnets.
One-sided magnetic and magnetic can be reflected in the magnetic rubber, rubber magnetic, if one side can be made on the single magnetic magnetic side are no magnetic, if is that both sides have a magnetic magnetic double.
If ndfeb, or other categories are magnetic, are both sides of you if you only need one side to a mask feng shell, such a magnetic big but the other side also have magnetic, is very small for many on the market structure of single magnet said confused, actually refers to a single magnet magnetic, magnetic weaker magnet on the other side, method is to use special processing of galvanized sheet will double the magnet one side of the package, so wrapped side will be magnetic screen cap, magnetic force is shifted to the other side, the other side magnetism will increase.
If some places need only one side of magnetic, can cause damage or interfere with the other side, such as magnetic;
On some occasions, such as packaging need only one side of magnetic magnet, dispensable, on the other side of magnetic is useless, so using a single magnetic will greatly reduce the cost and save magnetic materials.
The refraction of single magnet effect is mainly decided by the following three aspects: 1.
The selection of materials: materials and thickness, and the magnet and the spacing of materials have a close relationship.
Pure iron easy leakage, refraction increased after special treatment, but 100% of shielding materials haven't worked out, but has the different effect of different manufacturers do.
Angle: according to the principle of refraction, arc material effect is best, right Angle refraction material loss is bigger.
Space: the lines of magnetic force in the air like a mobile phone signal, it is necessary to have a space to reflect.
Flashlight lamp on the pot as completely wrapped in lamp, the use effect is not good, because a large number of light refraction are loss.
Single magnet application industry focused on: the moon cake box, printing and packaging, mobile phone box, wine box, tea box, gift boxes, bags, leather goods, computers, leather, clothing, white board to buckle.
Because of one magnet using zinc iron shell will double the magnet one side of the package, so wrapped side will be magnetic shielding, magnetic force is shifted to the other side, the other side magnetic enhancement;
To fulfill the requirements of ideal magnetic box, also can save the cost.
Magnetic stability is very important, of course, made the bad material magnet without sex will be a lot of, can let the user loss is very large.
