Earth is a magnet<\/strong><\/h2>\n\n\n\n<p>Our planet can be described as a huge bar magnet. Earth has\na magnetic north and magnetic south, that invisible magnetic field lines run\nfrom the north to the south. This is what a needle on a compass will point\ntowards.<\/p>\n\n\n\n<p>These magnetic north and souths are geographically different from the North and South poles.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>2. Magnets will always have two poles <\/strong><\/h2>\n\n\n\n<p>Magnets will always have two poles, magnetic north and magnetic south. <\/p>\n\n\n\n<p>Even if you cut them in half, the remaining pieces will still have a north and south.<\/p>\n\n\n\n<figure class=\"wp-block-video\"><video controls src=\"https:\/\/www.first4magnets.com\/blog\/wp-content\/uploads\/2022\/01\/North-and-South-GTK-GIF.mp4\"><\/video><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>3. Metal can become a magnet<\/strong><\/h2>\n\n\n\n<p>Stronger rare earth magnets can actually turn certain metals into magnets. Strong Neodymium magnets will be able to make ferromagnetic materials, such as iron, become magnetized. <\/p>\n\n\n\n<p>For example, a neodymium magnet can be rubbed against a screwdriver, making it magnetic allowing it to pick up and hold certain magnetic objects.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>4. The most powerful magnet in the universe<\/strong><\/h2>\n\n\n\n<p>Did you know that the most powerful magnet in the universe, is\na star? <\/p>\n\n\n\n<p>Well now you do, it\u2019s a magnetar! These are stars that have died and had a supernova explosion leaving behind what is known as a magnetar, these stars are actually strong enough to destroy small planets if they get close enough.<\/p>\n\n\n\n<p>A magnetar\u2019s field is about 1,000 times stronger than a normal neutron star and about a trillion times stronger than the Earth&#8217;s. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>5. MRIs are stronger than Earth <\/strong><\/h2>\n\n\n\n<p>Magnetic resonance imaging (MRI) is a scan that uses magnetic fields and radio waves o produce detailed images of the inside of the human body. <\/p>\n\n\n\n<p>MRI machines use extremely strong magnets and in fact, they generate stronger fields up to 60,000 times stronger than the Earth\u2019s. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>6. Animals can be affected by magnets<\/strong><\/h2>\n\n\n\n<p>Magnets have previously been used to study bee communication\npatterns, migratory cycles and several other animal behaviours.<\/p>\n\n\n\n<p>This is because many animals can actually sense magnetic fields birds, bees, whales, sharks, and turtles all use the Earth&#8217;s magnetic field to guide their behaviour.<\/p>\n\n\n\n<div class=\"wp-block-columns has-2-columns is-layout-flex wp-container-core-columns-is-layout-28f84493 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h2 class=\"wp-block-heading\" id=\"mce_6\"><strong>7. Magnets are ancient<\/strong><\/h2>\n\n\n\n<p>A long time before today\u2019s man-made magnets ancient civilisations used lodestones, a naturally magnetised piece of the mineral magnetite. <\/p>\n\n\n\n<p>Lodestones are naturally occurring magnets, which can attract iron. The property of magnetism was first discovered in antiquity through lodestones. <\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.first4magnets.com\/blog\/wp-content\/uploads\/2022\/01\/7f9f615b5de06d1428666781522141a8-250x227.jpg\" alt=\"\" class=\"wp-image-5027\"\/><\/figure>\n<\/div>\n<\/div>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>How much do you know about magnets?
