The earth is undoubtedly a planet that is rich in tremendous quantities of metals and minerals. Discovery of magnets on the earth’s surface has provided great contributions in the modern world and an example of the most used variety of magnets is the Neodymium disc magnet. This type of magnet has replaced various types of magnets, and is currently used in commercial applications in the modern products .Neodymium magnet is a permanent magnet that is made up of an alloy of boron, iron and Neodymium forming a crystalline structure.
Properties of Neodymium disc magnets
Neodymium magnet is classified according to the highest energy product with regards to the magnetic flux. They are mainly labelled from, for example N35 up to N52, where higher values indicate the stronger magnet.
Advantages of Neodymium Disc Magnets
Neodymium magnets are the most powerful in commercially produced magnets
The magnet has a harder texture as compared to other types of magnets
High grade neodymium magnet can operate in extreme temperatures
Neodymium magnets are also assembled using strong adhesives.
Disadvantages of Neodymium Magnets
Despite the hardness in most of the models under this type of magnet, the magnet may chip or break when dropped on a hard surface.
The uncoated Neodymium magnets may exhibit corrosion when used under humid conditions
Uses of Neodymium Disc Magnets
Coupled Magnetic pumps-Most magnetically coupled pumps are made of a motor driven shaft that has an attachment to a ring with powerful magnets. When the drive shaft is turned by the motor, the magnetic field produced, makes the other set of magnet turn thus powering the impeller.
Hard disk drives-The hard disk drive mainly records information by magnetising and demagnetising a relatively thin ferromagnetic film. Every disk is separated into many sectors made of small magnetic cells that are magnetised by the drive when data is written.
Doors-Neodymium magnets are used in residential and commercial buildings with an aim to create magnetic door catches. They easily hold the weight of a door.
Jewellery-Minute magnets are used in the manufacture of jewellery as well as clasps. The faces of the magnet in these products provide a secure hold.
Generators and motors-Electric motors and generators mostly depend on upon a combination of a permanent magnet and an electromagnet. The combination provides an easy conversion of electric energy into mechanical energy.
Neodymium disc magnets are great and durable products that are modified to fit into many applications to meet the customer’s needs.
