Introduction

Lightweight and small, NdFeB materials are the strongest permanent magnets available commercially. Having the most powerful magnetic properties among all permanent magnets, NdFeB magnets are a part of the rare-earth magnet family. NdFeB magnets are made from an alloy of neodymium, iron & boron and have high resistance to being demagnetized.

In modern technology, NdFeb magnets have replaced many permanent magnets as they have greater strength and hence can be used in smaller and lightweight forms. Let us explore the uses of NdFeb magnets in different fields and applications.

Application Fields

· Application of NdFeb in the field of communication technology

Due to their high strength and lightweight properties, NdFeb magnets are a great option for use in communication technology fields. NdFeB magnets are used for magnetrons, remote control, satellite communications, radar detection, and electronic tracking.

· Application of NdFeb in mechanical engineering

NdFeb magnets are strong permanent magnets that have a high magnetic strength-to-weight ratio. Hence, they pave the way for more compact motors. Motors are workhouses that convert electricity into power. Using this principle, these magnets are being used in a plethora of fields ranging from aerodynamics to the home refrigerator.

 Examples: Electric motors in cordless tools, hard disk drives, and magnetic fasteners. They also find their uses in speakers, VCM, magnetic cranes, magnetic machinery, etc.

· Application of Ndfeb in the field of transportation

With their high energy density, NdFeb magnets are a great choice for the automotive industry.  They are also being used in the aerospace, and wind turbine industries.

EV is a promising means of green transportation for better environmental sustainability. NdFeB Magnets are used in electric motors, wherein these motors convert energy to drive the EVs. Every EV employs about 2kg of NdFeB magnets, also, the demand for electric road transport applications could escalate in the next 5 years. Hence, as the sales of EVs are increasing, the demand for NdFeB magnets has gone up. 

Application of NdFeb in magnetic separation technology

The process of magnetic separation technology involves extracting magnetic substances from non-magnetic substances. These NdFeb magnets are available as magnetic tubes & rods, drum magnets, fishing magnets, or magnet filters. The magnetic tube is mainly used for filtrating powder, and magnetic impurities in a liquid or semi liquid.

The magnetic rod is widely used in the chemical & food industry, salvage of waste material, and so on. The drum magnet is used mostly in recycling industries. Drum Magnet separates ferrous impurities from slurries, granules, or powders. This industrial magnet works on a high-volume basis for applications and can separate even weak magnetic materials. Other industries where these magnets are used are mineral processing, coal, medicine, and water treatment.

Wrap-up

NdFeb magnets are available for a wide gamut of modern industries due to their robust properties of high strength, high-cost performance, good mechanical properties, and a wide range of applications.
