What do people use magnets for?

This is a very common question often asked when people talk about magnets. The simplest answer we can give is that “they are used in almost every commercial application across the world, from industrial manufacturing and consumer electronic devices to sustainable energy and domestic power generation”.

They were first discovered by the ancient Greeks and originally called ‘Lodestone’, they have been the subject of re-engineering and industrialisation for many decades. As a result, high performance rare earth magnets are now commercially available around the world. With the discovery of these small, high performance miracles came the development of new technologies.

The past decade has seen them form a fundamental part of consumer electronic devices. Without them the boom in computer hard drives would not have been possible, loud speakers would not perform so well and new wind turbine farms springing up around the world would cease to exist. They really are simply an unnoticeable part of everyday life.

What are Neodymium Magnets?

Neodymium magnets are often referred to “NdFeb” or "Neo". First discovered in 1982 and commercially available in 1984 Neodymium magnets have largely become the most widely used type of rare earth magnet around the world. They are manufactured from an alloy of neodymium, iron and boron (NdFeB). Although relatively small in size they are known for their incredible strength.

How are Neodymium Magnets made?

The main ingredients are Neodymium, Iron and Boron. The exact ingredients depend on the grade being produced. We also add a key ingredient called dysprosium to raise the coercivity of the material and increase the resistance to demagnetisation and corrosion. You can read more about the manufacturing process here.

Are Neodymium Magnets really that strong?

Yes, they are. Neodymium (sometimes referred to as “rare earth”) magnets are the strongest commercially available. They possess an extremely high magnetic pull and in some cases (the very strong ones) can cause severe injury. If you would like to know how some of our customers are using Neodymium magnets, please take a moment to view our Applications Page.

Our Product Range

If you know what type of product you are looking for but need some help finding it on our website, we have created a guide below to help...

Popular Magnet Materials

Here are our most popular materials...


Neodymium is the most powerful of all permanent magnet materials. They are often known as “Super Magnets”.They are used in applications where the strongest magnetic force is required from the smallest possible volume of material.

Flexible (Sheet and Tapes)

A range of high quality flexible magnetic material and ferrous material, everything from sheets with adhesive to sheets with brighly coloured vinyl facings.


Ferrite does not give the power of Neodymium but it creates deep depths of field and offers outstanding value for money.

Popular Magnet Shapes

Here are some of the most popular shapes available in our range...

Circular Disc & Rods

Circular discs can be fixed in place using adhesive or can be pushed into circular drilled holes in wood or plastic. We have one of the biggest ranges of sizes and materials available in the UK.


Including products made from N42 grade and N52 grade Neodymium magnet material, many of these magnets have unbelievable magnetic performances. A magnet 10mm x 10mm and 5mm long weighs only 4 grams and yet generates a force of over 2,800 grams.

Adhesive Backed

This range includes powerful neodymium discs with the convenience of super strong 3M adhesive with a peel away backing strip.
