The magnetic top spins over the base&#8217;s coil. This rotation generates a tiny electric current in the coil via &#8220;Electromagnetic Induction.&#8221; The &#8220;transistor&#8221; then captures this small current. The transistor acts like an &#8220;electrical amplifier,&#8221; which uses the battery&#8217;s power to boost the tiny, generated current into a powerful electrical signal.<\/p>\n<p>When this boosted electricity flows into the coil, the coil temporarily transforms into an electromagnet. This electromagnet applies a perfectly timed &#8220;kick&#8221; of force to the spinning top (magnet), assisting its rotation.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-53345 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2025\/04\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2025-09-28-5.53.07.jpg\" alt=\"\" width=\"250\" height=\"235\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2025\/04\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2025-09-28-5.53.07.jpg 452w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2025\/04\/\u30b9\u30af\u30ea\u30fc\u30f3\u30b7\u30e7\u30c3\u30c8-2025-09-28-5.53.07-300x281.jpg 300w\" sizes=\"auto, (max-width: 250px) 100vw, 250px\" \/><\/p>\n<p>In short, a cycle of \u2460Spinning \u2192 \u2461Electricity is generated \u2192 \u2462Electricity is boosted \u2192 \u2463Gets a kick from the electromagnet \u2192 \u2460Spins even faster&#8230; is rapidly repeated inside the base.
