Solenoid with a core definition of internal use of electric current through a coil to make it like a magnet has a magnetic device called a solenoid (electromagnet). Usually made of a bar or horseshoe. Core magnetization easy to use, and easy to disappear magnetic soft iron or silicon to the system to do. Such magnetic solenoid when energized, power outages after the disappeared. Electromagnet has an extremely wide range of applications in daily life. Electromagnet invention also makes the generator power has been greatly improved. Application electromagnet has an extremely wide range of applications in daily life. Electromagnet is a current magnetic effect (electric magnetism) of an application, are closely connected, such as electromagnetic relays, electromagnetic crane, magnetic levitation trains and life. DC solenoids and solenoid can be divided into two types of AC solenoids. If divided according to purpose solenoid magnet magnetic switch manufacturers can mainly be divided into the following five categories: (1) traction magnet - mainly used for traction mechanical device to open or close the valve solenoid magnet where a variety of incentives to perform Automatic control tasks. (2) lifting magnet - used as a lifting device for lifting steel ingot, steel, iron ore and other ferromagnetic materials. (3) the brake magnet - mainly used for motor parking brake in order to achieve an accurate aim. (4) Automatic electrical electromagnetic systems - such as electromagnetic relays and contactors electromagnetic system automatically switches the electromagnetic release and operating electromagnet and so on. (5) other uses electromagnets - such as grinding and electromagnetic sucker electromagnetic vibrator. Highest performance NdFeB magnetic one is soft, Mgnet magnet now two main categories. A magnet is hard magnetic. The concept includes soft silicon and which, soft core; hard magnetic including aluminum, nickel and cobalt samarium cobalt ferrite and NdFeB. The most expensive samarium cobalt magnet highest performance NdFeB magnets, ferrite magnets cheapest. But the best performance of the temperature coefficient of Alnico magnets, the most stable. The user can select a different hard magnetic products according to different needs. Said magnet lifting magnets, the magnets are generally refers to the permanent magnet. Permanent magnet is divided into two large magnets classification. The first category includes metal alloys NdFeB magnets NdFeB magnets SmCo magnets Alnico magnets Sm LNi second highest performance category ferrite magnets NdFeB magnetic material Ferrit. NdFeB magnets found in the commercialization of the highest performance magnets. Magnetic energy has a high maximum energy product BHmx than Ferrit times higher than the ferrite. Machining performance itself is also very stable, currently known as Magneto. The so its application is extremely broad. But because of its chemical activity is very strong, good. Operating temperature up to degrees Celsius. And its texture. There is a very good price. So essential to its texture rather hard, is a brittle material, from the appearance of the highest performance NdFeB magnet magnetic magnetic switch manufacturers | New Tong Xin magnetic | 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.
