Magnetic levitation photo frame using current magnetic effect makes the photo frame float in midair.At the top of photo frame there is a magnet, a coil of wire inside the top of circular plastic box, metal coil by current will become electromagnet.The suction between electromagnet and the photo frame top magnet can be offset by the gravity of the photo frame, so the photo frame can float in midair.Touch photo frame gently to deviate from the equilibrium position, the photo frame will return to the balance position and will not drop without hand.This is the use of negative feedback mechanism.Can put the two photos(12cm x 8cm) before and after or advertising and free rotation;Built-in 6 LED lights.
