5 Ways Magnets Can Help You Hang Your Christmas Decorations

Christmas is fast approaching and it’s the time of year when we risk life and limb to retrieve the old Christmas decorations from the back of the shed or that store cupboard that nobody ever seems to go in from January to November. While we can’t help you untangle the entwined mass of tinsel or figure out why the perfectly functioning lights of last year won’t now work, we can help make putting up your decorations much easier.

What Is A Reed Switch & Which Magnets Operate Them?

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... Read More

What Are Eddy Currents?

Not actually named after a fellow called Eddie - an eddy current is a swirling electrical current that is created in a conducting metal such as copper or steel by moving the metal through a magnetic field, or a magnetic field over the metal.

How to magnetise a screwdriver

If you are trying to fix a screw in a hard to reach place or are working with small, fiddly screws a magnetised screwdriver can save you lots of time. Most new, high-end screwdrivers are supplied already magnetised, but sometimes they can lose their magnetism. There are a number of ways you can use magnets to remagnetise a screwdriver, or magnetise one that was never magnetised in the first place.

Magnets and medicine

Magnets and medical research have a long and interconnected history. Life-saving diagnosis is made possible by MRI scanners that rely on the power of magnets, magnetic technology has a vital role in some of the most pioneering medical research and many believe in the opinion-splitting therapeutic benefits of magnets. This post will look at all three areas.

All about the Earth’s magnetic field

The Earth behaves like one large magnet; we know this for certain because of the visible effects on a magnetic compass by the Earth’s magnetic field. In 1600 William Gilbert was the first physician to publish his findings on the Earth’s magnetic field and a hypothesis for its origin in his book titled de Magnete.
