With the London Marathon this Sunday, everyone’s hard work and training will come into place as they take on tremendous challenge of 26 miles around the capital. It’s time to lace those trainers, plug in the ear phones and keep those legs motoring!
Google, the name synonymous with cutting-edge technology, introduces a new exciting platform, Google Cardboard. No, the Internet gurus at the Googolplex have not decided to diversify into origami, in fact they have developed a device that can be made out of cardboard (and a couple of magnets) that makes virtual reality affordable and accessible for anyone with a smartphone. In this article, we take a look at what all the fuss is about.
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
Neodymium magnets are the strongest in the world, that’s why they can be pricey. If you have an old hard drive (one you won’t ever need again), you can dismantle it to retrieve the neodymium magnets inside. Here I will give you a step-by-step guide for taking apart a computer hard drive.
Ordinarily, heat and electronics aren’t the best of companions; even less unsuited partners are heat and some magnetic materials!
However, a new technology being developed by Seagate for the next generation of storage devices, known as ‘heat-assisted magnetic recording’ is breaking the convention. The technology is heralded as revolutionary and could significantly increase the amount of data that can be stored on a hard drive by increasing storage density.
Since the days of the first personal computer it has been part of ‘geeklore’ (like folklore but more interesting) that magnets are bad for all things electronic. But come on I hear you say, we’ve moved on from the days of the faithful floppy disk and the cumbersome CRT monitor, surely this can’t be the case? Magnets can’t seriously damage my iPhone, can they?
