Permanent magnets do not need power.<\/strong><\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">Here is a table that shows the main differences:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><th>\ud2b9\uc9d5<\/th><th>\uc804\uc790\uc11d<\/th><th>\uc601\uad6c\uc790\uc11d<\/th><\/tr><tr><td>Magnetic Field Generation<\/td><td>Electric current creates the field<\/td><td>Magnetic field exists naturally<\/td><\/tr><tr><td>Power Requirement<\/td><td>Needs power to work<\/td><td>Works without power<\/td><\/tr><tr><td>Magnetic Field Control<\/td><td>Can turn on and off<\/td><td>Always active<\/td><\/tr><tr><td>\uc790\ub825 \uc138\uae30<\/td><td>Can change with current<\/td><td>Fixed strength<\/td><\/tr><tr><td>Cost and Availability<\/td><td>More expensive and complex<\/td><td>Easier to find and cheaper<\/td><\/tr><tr><td>\uc801\uc6a9 \ubd84\uc57c<\/td><td>Used in electronics, manufacturing<\/td><td>Used in motors, generators, loudspeakers<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Electromagnets can be stronger than permanent magnets if I use enough current.<\/strong> I can change how strong they are. I can also turn them on or off. This is good for machines that need switching. I use electromagnets in cranes, MRI machines, and relays.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Permanent magnets always have a magnetic field.<\/strong> I use them in motors, generators, and speakers. They do not need power, so they save energy. About 30% of all magnets in industry are permanent magnets. I count on them for steady work.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Key points to remember:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Electromagnets need electricity; permanent magnets do not.<\/li>\n\n\n\n<li>I can switch electromagnets on and off.<\/li>\n\n\n\n<li>Permanent magnets work all the time.<\/li>\n\n\n\n<li>Electromagnets fit jobs that need control.<\/li>\n\n\n\n<li>Permanent magnets fit jobs that need steady power.<\/li>\n<\/ul>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">I pick the right type for each job. If I need to control the magnet, I use electromagnets. If I need a magnet that is always strong, I use permanent magnets. Both types help me make better machines and devices. \u26a1<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"applications-of-permanent-magnets\">Applications of permanent magnets<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"600\" src=\"https:\/\/ct.semitanker.com\/wp-content\/uploads\/2025\/11\/7.-Applications-of-permanent-magnets.webp\" alt=\"7.
