Strong neodymium magnet applications and properties
Neodymium magnets, also known as Neo magnet are rare earth magnets that are also the most commonly used. The permanent magnet is made from the alloy of iron, neodymium, iron and boron. Neodymium magnets are the strongest type of permanent magnets that are commercially available. They have taken over from other magnets for use in many items requiring strong permanent magnets such as hard driver disks, cordless tolls and the magnetic fasteners. These magnets are used in various applications such as:
Hard disk drive
Strong neodymium magnets have replaced ferrite and alnice magnets in different areas of modern technology where there is a need for strong permanent magnets because of their greater strengths that makes it possible to use smaller and lighter magnets in any application. Some of the areas where these magnets are used include:
- Head actuators in the computer hard disks
- Pickups for magnetic guitars
- Magnetic resonance imaging(MRI)
- Door locks
- Head phones and loud speakers
- Electric motor
- Electric generators used in wind turbines
Other newer applications
On top of the above application, the Super Strong Neodymium Magnets can also be used in applications where magnets were not previously used. These include the magnetic jewelry clasps as well as the magnetic building sets for children. The strength and homogeneity that is in the neodymium magnets have made it possible for them to be used in new applications in the medical field such as the MRI (magnetic resonance imaging) scanners that are used in imaging the body in the radiology departments
Magnetic Properties
When searching for magnets, it is important to consider their properties. Some of the key properties used to compare permanent magnets include:
- Remanence. This measure the magnetic field’s strength
- Coercivity. This is a measurement of the resistance of the material to becoming demagnetized
- Energy product. The magnetic energy’s density
- Curie temperature. This is the temperature at which the a material loses magnetism
Why Neodymium magnets?
Neodymium Magnets for Sale are preferred as they have much higher energy product and coercivity as well as higher remanence. They have lower Curie temperature as compared to the other types. To preserve the magnetic properties of Neodymium while at high temperatures, it is alloyed with dysprosium and terbium. While you may be wondering what is it that makes the neodymium magnet to b ea supper magnet, it is the combination NdFeB that causes a high adhesive force even in the small magnets. This makes them stronger than the ferrite magnets of a similar dimension. You should consider buying a super magnet for use in a small and light product that will also be aesthetically pleasing.
