Magnet can generate a magnetic field to attract ferromagnetic material, such as iron, nickel, cobalt and other metals. When the point of wearing thin bar magnet, still, it is ultimately directed towards the north and south of the planet, and ultimately point to the north or north pole N, pointing to the south end of the guide rod or S pole. If the earth is like a big magnet, the Earth's magnetic pole means that in the Antarctic, referring to the geomagnetic North Pole South Pole. Magnets and magnet with magnetic poles repel Huizhou glasses case, between unlike poles attract. Therefore, guiding poles repel and guide poles, Arctic and Arctic magnet glasses case, refers to the rejection, and refers to the Antarctic and the Arctic attraction. With the development of digital technology, optical fiber communications and the Internet, for inductors, filters, chokes, demand for broadband and pulse transformer greatly increased their use of soft ferrite require μ (permeability) value is high, And want to increase the operating frequency. Usually called μi≥5000 high permeability ferrite magnet Foshan glasses case, the bulk material μi≥10000 stable production is not easy. In addition, with the increasingly widespread use of electronic technology, especially digital circuits and switching power supply applications, the popularity of the growing problem, the countries on the performance of electronic devices and equipment to the growing demands of Heyuan magnet glasses case, the new Xin Tong Magnetic, glasses box magnet provided by the Dongguan City Tong Xin magnetic Limited. Xin Tong, Dongguan City, the new magnetic Limited (www.dgxtxmagnet.com/) is Dongguan, Guangdong, magnetic leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the new Tong Xin magnetic leadership with the staff warmly welcome all inquiries to discuss, with new magnetic Tong Xin a better future.
