The Bermuda Triangle is notorious for strange phenomena and mysteries. While it’s probably more myth than fact, this peculiar part of the globe has captivated our imaginations for years. Well, those of us in the magnet biz have our own version—Russia’s Kursk Magnetic Anomaly. The Kursk Magnetic Anomaly, or KMA, is the world’s largest. Situated in southwest Russia near the Ukrainian border and its strange properties have puzzled scientists for years. What’s a Magnetic Anomaly in the First Place? As most of us know (especially if you follow us on Twitter), Earth possesses a magnetic field generated from millions of tons of iron and other metals deep within the planet’s core. Our magnetic field helps deflect harmful solar wind so we’re not irradiated. Strongest near the north and south poles, the magnetic field is pretty consistent across various degrees of latitude. However, there are of course exceptions to this rule. Often resulting from unusually high levels of metal, a magnetic anomaly is a change in Earth’s magnetic field that’s different from what’s expected. That means there’s such a large amount of metal in the crust, it can override the rest of Earth’s massive magnetic field! Why Are We Attracted to the Kursk Magnetic Anomaly? Plainly put, this site is massive. With more than 30 billion tons of iron ore spread across nearly 50,000 square miles, it’s the size of countries like Greece and Cuba. It’s so large, some estimate it accounts for about 50% of all of Earth’s iron ore reserves. Thanks to all that iron in the ground, compasses here will spin an extra 15 degrees, and in some areas, they even confuse south with east and north with west. This unique geological phenomenon has won the area the nickname “Earth’s Third Magnetic Pole.” Bottom line: If you decide to visit here, bring a guide. Much like the dreaded Bermuda Triangle, It wouldn’t be hard to get lost! But wait, there’s more! Thanks to all that iron ore in the ground, some parts are actually easier to navigate than others. That’s because the location is the perfect place for mining, and mining companies have cut enormous pits into the red surface all over the area to bring up the precious metal.
