Neodymium Magnets: An Introduction

In the early 1980s, neodymium magnets were developed and became popular in consumer products due to their high strength and even higher resistance to demagnetisation. The popularity of neodymium magnets has increased over the years as they are increasingly used in all types of consumer products. They can be found in a wide range of high-tech industries, including the aerospace, automotive, construction, computer hardware manufacturing and medical industries. Neodymium magnets are considered to be the strongest permanent magnets available, and they have many uses. Read on to find out more about how rare earth magnets are used.

Audio equipment

The demand for high sound quality from music players, mobile phones, and other consumer electronics over the last ten years has led to an increase in demand for high-performance speakers. Neodymium magnets have become an integral part of speaker design due to their unique properties that allow them to better respond to electrical signals. The use of neodymium magnets assists with an improvement in audio quality, which has led to a dramatic increase in demand for these types of speakers.

Hard disks

Hard disk drives are a vital part of digital storage solutions. The development of high-capacity hard disks relies heavily on the use of rare earth magnets, as they feature many smaller cone-shaped magnets that are positioned together to form one large magnet. Due to their high resistance to demagnetisation and durability, neodymium magnets are widely used. They maintain high product performance even when subjected to extreme shock or vibration, and their robust structure makes them ideal for use in this type of component.

Automotive industry

Neodymium magnets can be used in a wide variety of car parts that require increased performance through weight reduction and improved fuel efficiency. These high-performance materials are present in many car accessories today, including power steering, door locks and parking sensors.

Retail security tags

Neodymium magnets are widely used in security tag systems. These tags are attached to expensive merchandise, and when they are removed from the store, an electric field is created which alerts security staff of the attempted theft. The powerful magnets in these tags make it very difficult to remove them from the products. When a customer has paid for a product, the cashier places one side of the tag against something that is polarised to the opposite pole. The intense attachment which is formed as the agents pull together allows the tag to be released from the product.
