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
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
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
We sympathise with all of you who are having to home school during this lockdown! We completely understand certain topics may not be interesting to everyone, but we are a firm believer that magnets are a great teaching aid to allow your children to be interactive. It’s time for you to take charge and dismiss those blank little faces looking back at you. Here are our top magnetic tips and activities to help bring some fun back to home schooling! Make their workspace interactive! Our FerroPaint® magnetic paint allows you... Read More
It has been experienced by a majority of us, whether you were rubbing a party balloon on your head and sticking it to the wall or shuffling your feet across the floor to give your friends or family an cheeky little shock. Static electricity has occasionally added a spark to everyone’s day. Every year national static electricity day is celebrated on the 9th January. This day is dedicated to the observance of static electricity and investigates how we may cause it. Static electricity is vastly different from the electrical current... Read More
The biggest magnet on the planet is the earth itself. Today marks the celebration of the earth and in particular it remembers when French Physicist, Leon Foucault, revealed the Earth rotates on its axis! To celebrate we have put together some interesting facts to celebrate the Earth. Why does the earth rotate? “The Earth keeps spinning because it was born spinning” – Kevin Luhman, an assistant professor of astronomy at Penn State Rotating is known as the fundamental behaviour of objects in the universe. To help explain this hear is... Read More
In this article, we are going to show you how you can create the simplest (possibly), but by far the most awesome (definitely) DIY electric train by using nothing more than a battery, some bare copper wire and two magnets. Before you stand aghast in disbelief and tell us it can’t be done, make sure you check our article on how to make a basic electric motor with almost identical materials.
