There are two main types of magnets:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Permanent magnets: These are magnets that retain their magnetism forever, such as those in refrigerators or compasses.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Electromagnets: These only become magnetic when an electric current is passed through them. These are used in cranes, doorbells, and industrial machinery.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400\">Electromagnets can change the strength of a magnetic field by adjusting the current passing through them. This is an extremely useful invention in science and engineering!<\/span><\/p>\n<p><span style=\"font-weight: 400\">Magnets are magical objects that can attract certain metals thanks to magnetic fields. They have many applications in life, from toys to machines. Thanks to the magnetic field, magnets can attract magnetic metals, which is very helpful in life and science.<\/span><\/p>\n<p><span style=\"font-weight: 400\">Children can experiment with a magnet to discover more interesting things!
