Magnet Applications
Magnets are used in many different applications given their inherent strength in relation to mass and weight. Electromagnets, because they can be turned off and on, are used in powerful pieces of equipment and vehicles, such as magnetic-levitation, or maglev, trains. However, permanent magnets are also very versatile and strong components of myriad applications as well.
We’ve just begun an ongoing process of adding to this library, so if you don’t see your industry or application, please contact us and we’ll be happy to share our knowledge.
Common Applications for Permanent Magnets
As permanent magnets are often out of sight it is easy overlook the important role they play in modern life. Without permanent magnets, there would be no electric motors, loudspeakers, computers, hard disc drives, smartphones and many other commercial appliances. They also have a vital role in engineering, power generation, processing and manufacturing.
Common applications of Neodymium magnets
Neodymium magnets are the strongest magnets in the world. Neo magnets are frequently used for many types of consumer, commercial, industrial & technical applications where strong permanent magnets are required. Due to their high-magnetic strength, components that previously had to be large and heavy can now be miniaturized by using Neodymium (NdFeB) magnet materials. Common applications for neodymium magnets include:

We carry a large inventory of Neodymium magnets in disc, block, rod, segment, stick, arc, ball, tube and ring shapes, in a wide range of shapes, sizes and grades, available for customer purchase. We can also custom manufacture these to your exact specifications.
Common applications of Alnico magnets
Alnico magnets are relatively high in magnetic strength, offer excellent temperature stability and can be used in temperatures up to 1000°F (500°C), so they are ideal for many types of industrial manufacturing applications. In addition, Alnico magnets are manufactured through a casting or sintering process, so they can be made into complex shapes, not possible to achieve with other magnet materials. They are routinely used in the oil and gas, medical, aerospace military and defense, industrial automation, automotive, and manufacturing industry.

Common applications of Ceramic magnets
Ceramic (Ferrite) magnets are the lowest cost hard magnets available today, they have excellent resistance to oxidation and do not typically require additional protective coatings or finishes. Permanent ferrite magnets are commonly used in many applications where more powerful rare-earth magnets like neodymium magnets are not required. They are the preferred choice for all types of consumer, commercial and industrial applications. Common applications for ceramic magnets include:

Common applications of FeCrCo magnets
Iron Chromium Cobalt (FeCrCo) magnets are similar to Alnico magnets in magnetic property, but they have better mechanical property. Fe-Cr-Co alloys can be easily hot deformed and machined. There are practically no limitations of their shapes and sizes. They can be made to block, square rods, round rods, tube, strips, wire. FeCrCo magnets are beneficial combination of magnets and mechanical properties. Their maximum working trmperature can be as high as 400°C. Common applications for ceramic magnets include:

Types of Permanent Magnet Applications
Scientists use four basic ways to categorize magnets, based on how their magnetic force is used. We list the categories below along with permanent magnet examples.
Category 1: The magnet’s attraction or repelling force. These applications are the simplest use of magnets. A simple refrigerator magnet is a perfect example—a picture or slogan on a small piece of laminated cardboard with a small bar magnet glued to the back which attracts to a metal refrigerator door.
Category 2: The magnet’s ability to convert electric force into mechanical force.
Electric motors are good examples of using magnets to convert electric energy into mechanical force. While electromagnets are more commonly used for electric motors, permanent magnets can be used as well. A magnet is placed in a conductive substance, and then the magnetic field yielded by the magnet turns another piece of equipment, which rotates the motor rapidly.
Category 3: The magnet’s ability to convert mechanical force into electric force.
Generators predominately use this ability. In contemporary times, electromagnets are more often used for power generating turbines, but permanent magnets still play a part. Very simply, two permanent magnets are placed opposite one another, with like sides facing. Their repelling forces rotate a turbine, which then turns a piece of equipment known as an armature. This churning armature generates electricity, which can then be transferred to other purposes.
Category 4: The magnet’s ability to affect ion beams.
Cathode-ray tubes, a type of vacuum tube for focusing electrons, use permanent magnets for aiming purposes. A ring of permanent magnets, alternating north and south poles, is on the end of an electron gun’s yoke, and these ringed magnets can be rotated to focus the beam for better reception or tighter focus.
