Lifting Magnet In Mechanical Industry

Nowadays permanent magnetic materials are very widely used in electronic era. Such as electric toys, electric speakers, stereo Headset, computer drives and magnetic motor. Because of energy saving and environmental protection, its application is in full development.
Lifting magnet can be used in many occasions. Lifting magnet is used for lifting the iron and steel in metallurgical, mining, machinery, transportation and other industries. It is also can used as a electromagnetic mechanical hand to hold the steel.
This lifting magnet adopt fully  sealing structure and in good moisture performance. And this magnet is suitable for all kinds of lifting equipment because of it is in reasonable structure, light weight, large suction, low energy consumption, safety and reliability, easy to maintain and installation. The electromagnet with ultra high temperature type use unique thermal insulation. You should be careful in choosing lifting magnet. If the energized sustained rate is more than 50%, you can choose the high frequency type. If you lifting material in the water, you can choose the diving type. The parameters of diving type is same as normal temperature type. Certainly when the surface temperature of suction conveying material is higher than 600 ℃, you can choose super high temperature type.
Sometimes the lifting magnet work for too long time. For example the normal type has been used for about six hours, you should use standby mode. It means that use more than two to alternate work. Otherwise continuously for a long time will cause magnetic loss, lower operational efficiency, shortening of product life or even damaged disk.

Whether The Magnetic Field Is Harmful Or Not

People who work in magnet factory often be asked for many questions. The most common question is that whether the strong magnetic is harmful to people or not. We usually hear mostly words are electromagnetic radiation. Next we come to the specific analysis about this problem.
Firstly we should pay special attention to the physical damage of strong magnet or magnet with high strength. It is because that the magnetic force of the magnet is especially strong. So people must prevent injury. Such as suction to the blade will be stabbed hand.
Besides this problem is also magnetic field exposure problem that a lot of friends concerned. Generally speaking magnet manufacturer has not done related test and trial. While this aspect is not manufacturers technology. Engineers have referred to many related information. There is nothing information to indicate that the magnetic field is harmful. On the contrary there are a lot of productions attract consumers through the words such as  magnetic therapy health care in the modern market. So it seems that the magnetic has no harm to human body. Besides we must special instructions that strong magnet or neodymium iron boron magnet is harmless to the human body. But it not means that other big super is not harmless to the human body.

After The Magnet Breaking

Whether the fracture surface after the permanent magnet break off will attract each other or mutual exclusion, many people have debated with this problem. Everyone has his own opinion and usually the opinions are different. Some people think the position which the permanent magnet break off has contrary magnetic. But some others don’t think so. In fact, the most simple way to check it is test. After some tests, we will find that different shapes magnets will have different results.
From the test, the bar permanent magnet which we often see has opposite magnetic on the cleft. It means the two magnets that produced by crack will attract each other and can adsorption in a bonded together perfectly.
However you can not ignore other shapes of magnets, such as annular permanent magnet and pie permanent magnet. After the annular permanent magnet or pie permanent magnet cracked, the two magnet will have same magnetic. So the two can not attract each other. You make the two attach each other by force, but without any force, they will separate or even flip at once. 
Above all, we have known that whether the fracture surface after the permanent magnet break off will attract each other or mutual exclusion are decided by their shapes.
