Magnets have been popular in science classrooms for many years as a great way to learn about magnetic fields and poles, however, modern magnets can help children develop in a number of areas. Looking to teach your young child the alphabet, create an interactive space for them, or even challenge their mind with an ancient puzzle?
Looking to turn your wall into an interactive surface… well we have four magnetic options to help you create an interactive surface in your home or office! Our vast range of magnetic wall coverings and paint allow you to you create several different types of interactive surfaces around your home or workplace.
Our DIY decorations are perfect for the scariest night of the year, every year, and leave behind no damage, helping turn your home into a haunted house.
The process for manufacturing ferrite magnets, also known as ceramic magnets, is not as costly or sophisticated as producing rare-earth neodymium magnets. The chemical compound of ferrite magnets is SrO-6 (Fe2O3), a combination of strontium carbonate and iron oxide. Due to their chemical make-up it means they are extremely resistant to demagnetisation through heat and corrosion, although, like neodymium magnets they are very hard and brittle. Step 1 – Calcination The production of ferrite magnets begins with calcining a finely powdered mixture of iron oxide and strontium carbonate to produce... Read More
Alnico magnets have now been manufactured for over 100 years, in which time the process has not drastically changed. Alnico magnets are permanent magnets that are primarily made up of a combination of aluminium, nickel and cobalt but can also include copper, iron and titanium. In this blog we will be explaining the manufacturing process of Sintered Alnico magnets, smaller Alnico magnets, weighing grams rather than kilograms are usually created using the sintering process. Sintering is generally the process used when a high volume of magnets are required. . . Step 1... Read More
Samarium cobalt magnets are widely produced and the permanent magnets are primarily made up of samarium and cobalt but some grades will also contain varying small amounts of iron (Fe), copper (Cu), hafnium (Hf), zirconium (Zr) and praseodymium (Pr). A number of common manufacturing processes can be used to produce samarium cobalt magnets but typically, a method of reduction and melting is used followed by a process of bonding or sintering the raw material to form the magnet. Bonded Samarium Cobalt Magnets . . Step 1 – Heated Firstly, the... Read More
Alnico magnets have now been manufactured for over 100 years, in which time the process has not drastically changed. Alnico magnets are permanent magnets that are primarily made up of a combination of aluminium, nickel and cobalt but can also include copper, iron and titanium. In this blog we will be explaining the manufacturing process of Cast Alnico, a larger Alnico magnet weighing tens of kilograms which will nearly always be produced by casting. Step 1 – Foundry Furnace Each grade of Alnico has a special recipe in terms of... Read More
Our experts receive many questions regarding magnets, from how they work to how they are made – so with this in mind we have broken down the key information to answer the most common questions our experts receive to help you better understand the world of magnets! What is the difference between a permanent magnet and an electromagnet? A permanent magnet is a solid material that produces its own consistent magnetic field as the material is magnetised, however a magnetic field exerted by an electromagnet is produced by the flow...

Our magnets are used in an array of applications including filtration and separation to everyday objects like smartphones, one use of alnico magnets which may not commonly be known is in electric guitars. So, if you’ve ever been guitar shopping or though about learning to play, you’ll have stumbled across the term alnico pickups. But what exactly are alnico pickups and why are alnico magnets used? What are Alnico magnets? Alnico is an acronym comprising of the first letter of the three metallic elements used to produce the magnets Aluminium,... Read More
