Magnets come in many different forms and have an array of interesting properties. They are used by individuals, government and research organizations, educational institutions and industrial applications. The makeup of a magnet allows it to attract iron and some other metallic materials. Common uses of magnets in products include the strips on credit cards, compasses and decorative refrigerator magnets. They make attractive jewelry and fun toys and are behind the technology of magnetic resonance imaging or MRI. There are several different kinds of magnets. These include neodymium magnets and samarium cobalt magnets. What follows is some information on the basic properties of these different magnets, all of which are available for sale online.
Samarium Cobalt Magnets
These magnets are knows as permanent, rare earth magnets, and as the name suggests are composed of a samarium cobalt alloy. Though they are strong, they have a slightly weaker magnetic field than neodymium magnets, and are slightly more expensive. They have a superior ability to retain their strength under high temperatures, making them desirable in specific applications. They are used in space satellites, headphones, microphones and sensors. They are highly resistant to corrosion but can become brittle and chip. They are available for sale in many shapes and sizes, including bars, cylinders, cubes and discs. For custom grades and sizes contact a company representative.
These magnets are an alloy of neodymium, iron and boron. A neodymium magnet is the most popular of the group known as rare earth magnets. They combine high strength with low cost, making them very popular in a wide range of applications. They are 7 to 14 times stronger than ceramic magnets and are the strongest magnets on the market. They can be produced in many shapes and sizes, including discs, cubes, rings, wedges and spheres. They are ubiquitous in homes in the form of refrigerator magnets, earphones and jewelry cases.Common products such as iPads, hybrid cars, toys and premium speakers employ these magnets. They were invented only a few decades ago and have been rapidly replacing ceramic magnets in many applications.
These magnets, composed of aluminum, nickel and cobalt, are not as powerful as rare earth magnets. They are also not as inexpensive as ceramic magnets, so their usage is limited. They do, however, have specific properties that make them useful. They are reliable and stable in an environment where temperatures tend to fluctuate. They are resistant to corrosion so they don’t need coatings, except in situations where appearance is important. They are brittle, but can be formed into complex shapes such as horseshoes. They are used in coin acceptors, voltage meters, generators, sensors and radar bearings. They can be made into custom shapes
