Do you still remember the surprise that sparkled in your eyes when you first saw the toy move by itself? From the floating Iron Man to the mascot flapping its wings, behind these wonderful experiences lies a low-key "magic engine" - the ** micro electromagnet **. * * electromagnet is the core technology to realize toys magnetic levitation effect * *. In the Doraemon Maglev version launched by Kids Logic, the designer utilized the principle of buoyancy force of attraction and repulsion of electromagnets, allowing Doraemon wearing A bamboo dragonfly to truly "hover" on the base shaped like A dorayaki. The leaves of the bamboo dragonfly would also rotate slowly, perfectly restoring the flight posture. Similarly, the maglev version of the Iron Man Mark II by Egg Attack also simulates flight effects through electromagnets, elevating collectible toys from static ornaments to dynamic works of art. More surprisingly, electromagnet can also make toys with * * * * "vitality". In a patented mascot decoration, the control circuit makes the electromagnet change polarity at a certain frequency, causing the magnet on the movable wings to repeatedly attract and repel the electromagnet, achieving a dynamic effect of wing flapping. The cartoon figurine that can keep shaking its head, through the ingenious combination of an electromagnet and a permanent magnet, along with a swinging power generation mechanism, can achieve continuous shaking without the need to replace the battery. From magnetic levitation fly to clever fan wings, from automatic control to receive interest, electromagnet to * * low power consumption, high response, * * excellent performance, long life for toys into the infinite possibility. This tiny component hidden inside the toy is precisely the "magic engine" of the childhood's whimsical world, bringing every bit of imagination to life.
