What material is best for shielding a magnet?

Shielding a magnet or attempting to block a magnetic field is a subject that several of our customers approach our experts with on a regular basis, so we decided to examine what materials can be used to shield a magnet. Before learning how to shield a magnet it’s important to know that magnetic shielding does not block a magnetic field. No material can stop the lines of flux from travelling from a magnet’s north to its south pole. However, it can be redirected. The simplest example of this would be... 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

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

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;...

Your Frequently asked questions answered

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...

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
