The good news is we have 6 facts about magnets that you don\u2019t know\u2026 yet.<\/strong><\/p>\n\n\n\n<p>Magnets are used in all walks of life day to day, some you may not see or remember their use and some you might not even be aware of!<\/p>\n\n\n\n<p>That\u2019s why it\u2019s essential to know as much as possible about magnets. So, check out our top 6 facts about magnets that you need to know.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>1. Magnets Have Two Ends<\/strong><\/h2>\n\n\n\n<p>Every magnet has a north pole and a south pole.<\/p>\n\n\n\n<p>A magnet\u2019s poles are the surfaces from which lines of magnetism leave a magnet and reconnect on return to the magnet. The pole of a magnet is the area that has the greatest magnetic field strength in a given direction.<\/p>\n\n\n\n<p>Magnetism either attracts or repels objects, if the same pole of two magnets are placed close together they will repel and push away, whereas two different poles placed near each other attract and pull together.<\/p>\n\n\n\n<figure class=\"wp-block-video\"><video controls src=\"https:\/\/www.first4magnets.com\/us\/blog\/wp-content\/uploads\/2022\/01\/North-and-South-GTK-GIF.mp4\"><\/video><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>2. Magnets Produce A Force<\/strong><\/h2>\n\n\n\n<p>All magnets produce a magnetic force, this is called a magnetic field. This field travels from a magnet&#8217;s north pole to its south pole and is completely invisible to the human eye, however, <a href=\"https:\/\/www.first4magnets.com\/us\/other-c89\/iron-filings-0-18lbs-science-education-1x-0-18lbs-bag-p3818\">iron filings<\/a> can be used to show these fields.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>3. Not All Metals Are Magnetic<\/strong><\/h2>\n\n\n\n<p>Magnets only attract certain types of metals including nickel, steel, iron and cobalt.<\/p>\n\n\n\n<p>Most metals such as copper, silver, aluminium, platinum, magnesium and gold are not magnetic. Other objects such as plastic, paper and wood are also not magnetic.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.first4magnets.com\/us\/blog\/what-metals-do-magnets-stick-to\/\">Discover What Metals Magnets Stick To Here<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>4. There Are Different Types of Magnets<\/strong><\/h2>\n\n\n\n<p>There are three different types of magnets including electromagnets, air-core magnets and permanent magnets.<\/p>\n\n\n\n<p>There are five types of modern permanent magnets, each made in a different way from different materials with different characteristics.<\/p>\n\n\n\n<p>The five types of permanent magnets:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/www.first4magnets.com\/us\/neodymium-t137\">Neodymium<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.first4magnets.com\/us\/samarium-cobalt-magnets-t140\">Samarium Cobalt<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.first4magnets.com\/us\/ceramic-magnets-t138\">Ceramic<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.first4magnets.com\/us\/alnico-magnets-t139\">Alnico<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.first4magnets.com\/us\/flexible-magnets-t141\">Flexible Rubber<\/a><\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image aligncenter\"><a href=\"https:\/\/www.first4magnets.com\/us\/shop-by-material\"><img decoding=\"async\" src=\"https:\/\/www.first4magnets.com\/us\/blog\/wp-content\/uploads\/2022\/01\/Banner-Image-for-blog-700x140.png\" alt=\"Magnetic Materials\" class=\"wp-image-731\"\/><\/a><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>5. The Earth is a Large Magnet<\/strong><\/h2>\n\n\n\n<p>Earth\u2019s core is made up of mostly iron, which has given the Earth its own magnetic field, with both a north and south-facing pole. The Earth\u2019s magnetic field protects the planet by deflecting solar winds and charged particles from the sun.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>6.
