Father’s Day 2017 is right around the corner and the team at FIRST4MAGNETS® are helping you to find the ideal gift! Now, however grateful your Dad may seem when he says, “thanks for the socks” he probably isn’t that impressed. This year we are giving you the ammunition to impress with our diverse range of magnetic gifts for Dad!
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 today we’re giving you the chance to do the same with our step by step guide! In 4 easy steps you could have an amazing magnetic trick to show your friends and family.
May the magnetic force be with you!
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…
A reed switch is an electromagnetic switch used to control the flow of electricity in a circuit. They are made from two or more ferrous reeds encased within a small glass tube-like envelope, which become magnetised and move together or separate when a magnetic field is moved towards the switch. The switch effectively works like a gate, or a bridge, in an electric circuit so when the two reeds are in contact, electricity can flow around the circuit operating a device. Unlike mechanical switches they do not require something or someone to physically flick them on or off, they are controlled completely by invisible magnetic fields! Continue reading
Magnets are fascinating – there are many things about magnets for which the only explanation seems to be magic! The best place to find out about magnet-related phenomena is of course here, on our blog – and YouTube. The most viewed videos showing super-strong magnets falling through copper pipes alone have amassed an incredible 8 million views and counting.
What you are seeing in these videos is of course a demonstration of eddy currents in action. Here we will explain what is going on.
In our previous blog article we took a look at how a DC and an AC motor works and described how you can build your own basic DC motor. Even simpler than a basic DC motor, is a homopolar motor. First created in 1821, it really is the simplest example of a motor possible, and really easy to experiment with.
When we talk about magnetic levitation what we are referring to is an object suspended by magnetic pressure which counteracts the effects of gravity. It generates images of large futuristic objects hovering and travelling at high-speeds.
Yesterday, Tuesday 8 October 2013. English Professor Peter Higgs and his Belgian colleague François Englert were awarded the Nobel Prize for their work that proposed the mechanism that explains how the most basic building blocks of the universe have mass. The Higgs Boson theory.
