However, unlike\npermanent magnets, the magnetic field produced by an electromagnet is produced\nby the flow of electric current and will disappear when the current is turned\noff. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, an electromagnet typically consists of many turns\nof copper wire which form a solenoid, when an electric current flows around the\nsolenoid coil, a magnetic field is created. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If an iron core is inserted into the bore of this solenoid,\nthen magnetism is induced into it and it becomes magnetic, but when the current\nstops flowing it immediately becomes nonmagnetic. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Both permanent magnets and electromagnets have North and\nSouth Poles, and both will have their magnetic fields interact with other\nsources of magnetic fields and materials which exhibit magnetic properties. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here\u2019s a breakdown of the similarities and differences between permanent and electromagnets:<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter\"><img decoding=\"async\"
