How are Alnico magnets important to electric guitars?

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

How are Ferrite Magnets made?

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

How are Neodymium magnets made?

Neodymium magnets are technological marvels and the process for creating them is sophisticated and delicate. The main ingredients of a neodymium magnet are neodymium itself, iron, and boron; the chemical compound known as NdFeb. The exact ingredients depend on the grade or strength of magnet being produced. However, the production process for different strength magnets sees the same size different stages required to produce a neodymium magnet. . Step 1 – The Mix Firstly, all the elements to make the chosen grade of magnet are placed into a vacuum induction... Read More

How is the strength of a magnet measured?

When considering the ‘strength’ of a magnet there are several key measurements that all contribute to a magnet’s strength in different ways, which can be a little confusing. Also, when trying to determine or measure a magnets strength the answer will be dependent on what is meant by strength be it either the pulling force or magnetic field strength, which are both often referred to as strength. So below we will describe each attribute that contributes to a magnets performance and in turn answer the question how is the strength... Read More

Handling Magnets Safely

Magnets can be extremely useful and have many benefits for a wide range of applications, but they do come with some hazards. If you place two magnets close to each other you will see them attract, in which they leap towards each other with great acceleration and then slam together. All our magnets are tested, and each magnet is clearly labelled with its pull-strength and our stronger magnets are packaged alongside a warning brochure. Neodymium magnets are amongst the strongest magnets in the world, and the force at which they... Read More
