Since 2002 , focus on manufacturing and supplying various kinds of bonded ferrite magnets


Recently very hot topics of the magnet mobile rack have an impact on mobile phone?

For small magnetic magnet ( Small magnets on such as mobile phone holster, cell phone support, etc. ) Is will not affect the function of the phone, please rest assured to use! If the magnet magnetic larger best away from mobile phones. Has little effect, the surface magnetic force over a certain range. Now on the market of mobile phone basically use the magnet, its internal magnet is done under 200 gs, the better the phone internal magnetic separation, the better. So, for mobile phone bracket, the surface magnetic ( Part of the contact phone) More than 200 gs will impact on the phone, or even damage. Just now on the market of magnetic phone support, are more than 2000 gs, is ten times bigger than the standard values. Such as a result of the mobile phones of electromagnetic signals and magnetization is interference within the iron parts, gradually lead to collect navigation misalignment and failure, call quality distortion, caton operation, data loss, screen, screen or black screen, intermittent crashed, until the scrap. The above phenomenon would have occurred in 1 to 4 months, depending on the cell phone also can appear different situations. This also has a professional testing institution, but need at least a year to discriminant identification of exactly how much the influence of mobile phones, only professional magnet manufacturers and mobile phone manufacturers can use instrument to measure the specific value for yourself. Suggest to buy magnetic stent should choose to cover plate ( Stick it on the back of the phone, no no) After the surface of magnetic force under 200 gs. Give a simple test method: on the phone support to cover feng iron the back of the phone, a round coin rolled from above, will not absorb basically only a few hundred GS, too much will absorb the coin, does not suggest to buy. Magnet company is the specialized production ( Ndfeb) Powerful magnet company, has factories in dongguan city based wangniudun pier town. Magnet products used in toys, jewelry, crafts gifts, handmade gift box, leather handbags invisible magnetic button, plastic hardware products, audio equipment and other industries. Our company is located in dongguan city based wangniudun block cao beijiao town five chung village industrial zone, the company can provide customers 24 hours delivery, 36 hours to the customers specifications template. Magnet experts will find magnet products co. , LTD. , dongguan city, pack your satisfaction, more information you can view our company website/magnet. This article rigorous reproduced, if there are any violation, the consequence is proud! 1, accessories of magnetic after years of use easy to affect signal 2, apple 4 s at the bottom of the screw also started using 410 stainless iron screw, magnetic tape, but after years of use will affect the signal, the back of the apple 5, screws are used without magnetic. Magnetized and Chinese found in nature in ancient Greece there is a natural stone, called it a 'tool'. This stone can be magic little pieces of iron absorption, and at a random wobble is always point to the same direction. Early voyager the magnet as the compass of its first to identify the direction in the sea. After one thousand years of development, the magnet has become a powerful material in our life today. Through the synthesis of different material alloy can achieve the same effect as the tool, but also can improve the magnetic force. Came in the 18th century artificial magnet, but the process of making stronger magnetic material is very slow, until the 1920 s to produce the aluminum nickel and cobalt, Alnico) 。 Then, in the 1950 s produced the ferrite ( Ferrite) , creating a rare earth magnet in the 70 s [ Rare Earth all including ndfeb ( 钕铁硼) And samarium cobalt ( SmCo) ] 。 At this point, magnetism obtained the rapid development of science and technology, strong magnetic material also makes the components more miniaturization. Magnet products co. , LTD. , dongguan city site does not arrange the position, everything is equal to zero technical support: all network company address: China guangdong dongguan dongguan city based wangniudun town pier five chung industrial zone telephone: 0769 - The 81313183 guangdong ICP for 16113157
