What Are Magnets? | The Fact Site

The earliest magnets were of course found naturally just lying around. These were found in rocks and other types of earth known as magnetite or lodestone. The story goes, the founder discovered the mineral after finding the nails of his shoes stuck to a magnetite rock. Others says it was the Greeks or the Macedonians, or even our good friend, Pliny the Elder. One thing is for certain though – the first magnets were simply lying around for millennia before our discovery.

And now, some fun facts about our magnetic friends! The biggest magnet in the world there is reference to, is actually found in Switzerland in the scientific wonder we all know as the Large Hadron Collider. The Hadron Collider has a reasonably weak strength of 40000 Gauss, which, to put it into perspective, is 400 times the strength of an average fridge magnet. This contraption is used to investigate subatomic particles and part of the hunt for the so-called, “god particle,” but this is a topic for another day.

One of the strongest magnets in the world, is of course smaller than the Large Hadron Collider. This is often the case with strong magnets. One is actually found in Florida State University. It cost an insanely large sum of $2.5 million, but comes in at a staggering 25 Tesla. To put that in perspective, 1 Tesla = 10000 gauss, so this means it comes in at around 2,500 times stronger than a fridge magnet, or 25 times stronger than a magnet used in a scrapyard.

Another interesting fact is that Scandinavia actually has the largest amount of magnetic material in the world. If you place a wooden plank in water with a magnet attached and allow it float, the magnet will point its northern pole to Earth’s North Pole.

So there we have it, magnets, something we use every day of our lives and have benefited us in more ways that we could ever imagine. One thing is for sure though – there’s no escaping the magnet. Even the world is one big magnet if you think of it – it’s polarized with a magnetic north and south pole. Indeed, the very same ones the penguins and Santa live on!
