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

What metals do magnets attract to?

Several customers will contact our team of experts to enquire about what materials will our magnets stick to, as magnets will not stick to all metals. Understanding what metals are magnetic and then learning which metals are best for use in your applications is important. So, here at FIRST4MAGNETS we have decided to show you what magnets will and won’t stick to and explain the reasoning behind these answers. Metals that attract to magnets Metals that naturally attract to magnets are known as ferromagnetic metals; these magnets will firmly stick... 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

What reduces a magnets performance?

All magnets have a ‘pull’ rating measured in kilograms which relates to how much force acting perpendicular to the magnet to pull the magnet from a steel plate, when in direct contact. The ‘pull’ rating is obtained and calculated under ideal conditions such as a thick enough steel plate which is perfectly flat and clean. As the pull force is slowly steadily increased and is absolutely perpendicular to the magnet face. However, in real world applications, perfect conditions are unlikely and there are six main factors which could affect and... Read More

Are Magnets stronger when side by side?

Does placing two magnets side by side double the pull force? We get questions like this from customers regularly about how different set ups of magnets will affect their performance. The answer truly to this question is it depends on the exact circumstances and set up you are using for your magnets. So, we decided to look and explain what the results would be when placing two magnets side by side. The pull force of two magnets side by side attracting to a steel plate can vary in several ways;...

Commemorating Earth Rotation Day

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

How does the International Space Station use magnets?

Did you watch the space launch on Saturday? We certainly did! SpaceX Dragon has successfully launched into space on Saturday 30th May 2020 and has now arrived at the International Space Station (ISS)! This is an incredible achievement within space history. Here are some fun facts and research done by ISS with the use of magnets! FOOD AND DRINK In space you can’t simply place something on a surface and walk away from it. It is reported astronauts often lose things and can spend their time searching for lost items.... Read More

Magnets in space

Who’s excited for the SpaceX launch on Saturday? We certainly are! For those of you unsure, Nasa and SpaceX are making history this Saturday 30th May, by launching two astronauts into space from US soil for the first time since 2011! Robert Behnken and Douglas Hurley are due to travel to the International Space Station (ISS) at 8.22pm UK time, in a spacecraft built by billionaire entrepreneur Elon Musk’s company. If successful, this will be the first time this act would have been performed by a privately-owned company. The mission... Read More

Our Experts’ Favourite Magnets: David Gault

Welcome to the penultimate episode of our Experts’ Favourite Magnets series. It’s a sad day as we conclude our 5th and final post. Fortunately, we have Mr David Gault, the Head of Production at Magnet Expert, revealing his favourite magnet to us today! But before we get started, lets recap the last few weeks. We started off with Juan who was a big fan of the Feel Flux Skills! Then we moved onto the Head of Sales & Marketing, Mr Simon Elliott whose favourite magnet was the Neodymium Clamping Magnet with...

Our Experts’ Favourite Magnets: Nathan Wallace

Welcome to week 4 of our Experts’ Favourite Magnets series. Over the past few weeks, our experts have revealed their favourite magnets and how you can use them at home or at work. Sadly, we are nearing the end of our blog post series with only 2 experts left to reveal their magnets *crowd gasps* … but don’t be too downhearted, we’ll be back with more great content! Today, Nathan ‘Mason’ Wallace takes the time to tell us about his magnet of choice. In keeping with tradition, here’s a bit... Read More
