All about rare earth magnets
Rare earth magnets are a special type of magnet, first manufactured in 1970. They are made of metal rare earths are a group of seventeen elements found in the periodic table. These include scandium and yttrium, despite the name, actually found in abundance on the Earth's crust. Rare earth magnets have the distinction of being the most powerful type of permanent magnet. They are much stronger than the known ferrite or alnico magnets. rare earth magnets can produce a magnetic field is stronger than 1.4 Tesla, while the other fields of 1 tesla or less. Magnets rare earths are powerful, mainly because they have what is known as high magnetic anisotropy. High anisotropy means that the crystals in metals rare earths are easily magnetized in a specific direction, but difficult to magnetize in other directions. These magnets also have high coercivity, which which means they have a strong resistance to the loss of their magnetic properties. However, they are also very fragile and easily rust. Usually are covered with some type of coating or coating to prevent chipping or broken. Also, if you want to buy rare earth magnets that need to be aware that they are considerably more expensive than other types of magnets.
The two types of rare earth magnets are samarium-cobalt and neodymium. Sarium-cobalt type was first invented in the decade of 1970, and is more brittle and weaker than the type of neodymium, which was invented about a decade later. The type of samarium-cobalt also is more expensive. However, it has the advantage of a higher Curie temperature, which means it can be used at higher temperatures without losing its magnetism. The type of neodymium made of neodymium, boron and iron, are much more widely used.
rare earth magnets, are not normally used as refrigerator magnets or other than consumers often use alnico and ferrite magnets, due to its cost. They are used primarily industrial, appliances and parts. One of the most common industrial uses earth magnets rare in most hard drives on your computer. Also found in speakers and headsets, cordless tools, and mag-lev trains. As prices have fallen in recent years, consumers increasingly buy rare earth magnets for domestic purposes such as finding nails in the floor, erasing video tapes, Connection auto tarps, old or magnets magnetization re-alloy steel that have become demagnetized.
The best way to buy rare earth magnets is to go online and do some patient search. Use a search engine like Google or Bing, and start with a search term such as "buy magnets "or" magnet prices ". Be sure to see a large number of websites before making any decisions. Make sure the store has a policy reasonable return, and there are no hidden costs such as shipping costs.
