The Role of Rotation in Magnetic Levitation

Researchers have conducted a detailed experimental analysis to explain the forces behind magnetic levitation using a spinning magnet. The study reveals that the levitation phenomenon is caused by slight tilts in the magnetic axes of the magnets relative to their rotational axes. The researchers found that the spinning magnetic field of the rotor magnet exerts a torque on the levitating magnet, drawing it into a locked rotation. The levitating magnet assumes a vertical orientation with a few degrees tilt, resisting the torque that would align it parallel to the rotor magnet. The system has potential applications in contact-free manipulation of objects.
