In a groundbreaking development, researchers from Université Paris Cité and the Laboratoire de physique de l'ENS Lyon in France have developed a simplified model to explain magnetic levitation. This model, validated by experimental measurements, sheds light on a phenomenon first observed in 2021.
The experiment involves suspending a magnet using magnetic interactions. A rotating magnet, tilted slightly, creates a magnetic field that allows another magnet to levitate at a fixed distance below it. The rotating magnet spins at a frequency of 150 to 300 Hz.
The model highlights that the levitating magnet is trapped by a combination of attractive and repulsive magnetic forces. The attractive force comes from the rotor's tilt, while the repulsive force comes from the levitating magnet. This could lead to advancements in transportation, such as the Maglev trains.
