subject: What Gives Rare Earth Magnets Their Value? [print this page] The rare earth magnets have a great value because of their magnetic qualities. The materials are not as important as the magnetic properties. These magnets appeared between the years1970 and 1980. These rare earth magnets are very strong and long lasting. The price for these rare magnets is also very high. Usually magnets are rated according to their properties. The durability and the power of the magnetism are very important for deciding the rating of magnets. Nowadays, the most used magnets are the Samarium and the Neodymium. These magnets have some great qualities.
You can compare magnets only by knowing their magnetic strength, power to stay magnetized and density. The Curie temperature is also very important. This represents the temperature at which you can lose the magnetism. You may have to pay more money for Samarium?cobalt or Neodymium magnets. However, you need to keep in mind that these are some of the best magnets you can find. They can be used in a wide variety of industries. For example, the Samarium magnet can maintain its properties even at a higher temperature. This is the reason why Samarium is one of the most expensive magnets.
The crystalline structure is very important for magnets. The rare earth magnets can provide some amazing qualities because of their electrons.
It takes a lot of time and money to create permanent magnets. These are made from minerals and metals like iron or cobalt. The process can be very complicated. For example, solids parts of metals should be covered in a special powder. In order to complete the magnetizing process, the block should be heated up to 1000?C. This temperature will allow the melting of Neodymium.
It?s important to know that the magnets can have a few built-in problems. One of the issues is that they can corrode very fast. You should be very careful when handling these metals. This way you can avoid any cracking or fracturing. The magnets can have a very big strength. This can even cause injuries. Even two little pieces of magnets can hurt people. Some of the injuries can cause broken bones. This is why you should get well informed before handling rare earth magnets. Remember that if they are close together their strength will increase. The magnets can smash together with a very big force. In this case the magnets can lose their brittle material.
The rare earth magnets are very popular because of their durable magnetic field. The cost for these magnets is high because they are used in a lot of industries. The earth magnets can be used for creating a lot of things to improve people?s life. These magnets are considered to be rare because of their amazing qualities and properties.
