For lifting of steel plate length shorten half, which do not need to use the original number of permanent lifting magnets , can be done by shorten telescopic beam. Telescopic lifting can lift and move cargo beyond of the original working area in the operation of signal beam. Especially when there are obstructions (such as column, etc.) can increase the auxiliary working area, making special object or equipment can make full use of its service space. If customer needs to lift the work piece out of the scope of hanging, he can use the solution of telescopic crane. Adjustable beam supported by girder can be hanging out of 2 m distance of the track to one side or both sides, can service to new lifting outside area and difficult to close to area. Customers can according to their actual use choose required overhanging and telescopic size. The characteristics of electric permanent magnets Neodymium Magnets used for telescopic crane: Electric control PM lifting doesn't need electricity in work, attracting work pieces by permanent magnet, avoiding the danger of the objects fell off due to the magnetism loss of the lifting electric PM in sudden power lost or connecting cable damage. Electric permanent magnet can produce powerful suction to 16 kg/cm squared, no attenuation with the extension of time, with great security. While the electromagnet has limited magnetism holding time after a power outage, a long time power cut is easy to cause accident. Electric PM spreader can be equipped with a ground detection function, the demagnetization operation is effective only when the lifting landed completely, avoiding the risk of wrong operation. Electric control permanent magnet jack use electricity within 0.1 ~ 2 seconds of magnetization and demagnetization, the electromagnet save power consumption by more than 95%. The control system is simple, and electric PM body and control system are light weight, can reduce lifting equipment load, increase the lifting weight, improve equipment utilization. Battery is required for the electromagnet maintains magnetism in power cut, so the electric permanent magnet is more environmentally friendly. View Details

Magnetizing water could increase water enzyme activity and membrane permeability. Frequently drinking magnetized water enhances physical health, regulates the body's circulatory system, digestive system, endocrine system and neural function, and improves human immunity, which is beneficial in the prevention and treatment of various diseases. In the descaling industry: After highly magnetized by neodymium magnets , deformation of the angle and length occurred to water molecules at the same time, with angle of the hydrogen bond decreased from 105 degrees to 103 degree, physical and chemical properties of water changed, water solubility and activity greatly improved, and calcium carbonate in the water decomposed into softer calcium bicarbonate during stewing process, which is easy to be swept along with water without accumulating on the wall. Besides, polymerization degree will be increased, and the dissolved solid matter becomes finer particles. The distance between two single ions becomes smaller so they are not easy to congeal on the wall cleaning effect is achieved. Environmental protection and energy saving property of neodymium permanent magnets are becoming an important factor in the development of the manufacturing industry in various countries, and neodymium magnet is one of the main raw materials for environmental protection and energy saving products. The application of neodymium rare earth magnets in the automotive, compressor, wind power generation and other fields is out of such consideration. As an environmental friendly material, the application of neodymium magnets will be more widespread. In an era of increasingly nervous energy, conversion of wind energy into electrical energy will undoubtedly be subjected to government policy support. Wind power has been implemented on a large scale in Europe. 1 MW generating unit takes roughly 1 ton neodymium iron boron. Thanks to the rapid growth of the wind power industry, the consumption of amount of NdFeB permanent magnets in the wind turbine will also be in a rapid increase. View Details

To figure out this question, we shall note the following points: 1. The reason why a magnet has magnetic force is that it is actually composed of very small lattices. The characteristic of these lattices is that they have a ring current (formed by electron motion) around certain axis. And the axis of ring currents is almost the same. A loop current can be seen as a tiny magnet, and magnetically stronger magnets are just composed by a large number of these tiny magnets with same N and S poles. 2. Under natural conditions, the small lattices inside permanent magnets are in steady state, which is in the lowest energy state. Objects always tend towards the lower energy state, so circular current direction will not change. To demagnetize a magnet, the circular direction of tiny lattices must be disordered, which requires input of external energy (for example, to heat it up to a high temperature). So under natural conditions, magnets will be in a stable state, which is permanently retaining its magnetism! In What Case, Magnets Lose Magnetism Commonly, magnetic performance is most sensitive to heat. Any material has Curie temperature, T. Under the temperature higher than T, magnetization direction of the material will be the same as the outer magnetic field as you put. The material has no magnetism if you don’t put any magnetic field outside of it. This is called paramagnetism. On the other side, when Curie temperature is under temperature T, atoms of the material are inclined to form magnetism in one direction (obviously, you can guide the magnetism to point to the direction you want). It is called ferromagnetism. Curie temperature of most materials is low. Most of them do not have spontaneous magnetism under room temperature. Human discovered that although some materials have high Curie temperature, they have ferromagnetism under room temperature. These materials can be made into common magnets. Therefore, permanent magnet will lose magnetism when Curie temperature exceeds T. Every atom of crystal will point to a new direction. But magnetism of each crystal point to different direction, so they seem not magnetic. However, if you put magnetic field outside a magnet if temperature decreases, crystals will be guided to point to the same direction and the magnet will get magnetism again. Magnets are always made in that way. View Details
