Описание: Have you Ever seen something so small it can hide inside your fingerprint
This tiny piece isn’t dust it’s the rotor of the world’s smallest motor!
It’s so delicate that if it slips once, it’s gone forever.
Scientists use it in micro drones
and when combined with four electromagnets and coils,
it gives them power to fly freely without any wires
