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
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;...

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
When you think about the many applications that First4Magnets’ Neodymium Magnets can be used for, the first thing that comes to mind might not be levitation. However, as you can see below, that’s exactly what the creative guys over at the Tonbridge School Physics Department have used them for!
May the 4th be with you this Star Wars Day! For those who don’t know, Star Wars Day, formally known as May 4th, is a day where enthusiasts come together to celebrate the franchise! For instance in Sydney, one local burger bar has launched the Star Wars burger and here in the UK, entertainment stores are slashing prices on retro Star Wars games! Here at FIRST4MAGNETS.COM, we are no different and we’re celebrating Star Wars Day with magnets! Our experts have been working with Darth Vader himself to levitate coins and... Read More
Find out about British Science Week and how you can get involved! Science is in the air as British Science Week 2017 gets underway! From the 10th – 19th March, a ten-day celebration of science, technology, engineering and maths begins with schools, science enthusiasts and professionals getting involved in a range of events across the UK! Here is everything you need to know…
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.
At first4magnets, we recently got hold of some super slow motion cameras. Naturally. after having fun using them to film large neodymium magnets squashing things in 2000 frames per second, we thought it would be interesting to shoot a permanent magnet Gauss rifle in slow motion and explain how one works…
