The phase angle, φ, between the floater and the rotor magnets. The phase angle is the angle between the projection onto the x–y plane of the respective magnetization vectors of the two magnets, mr and mf. The levitation distance is the center-to-center distance between the rotor and the floater magnets. Credit: Physical Review Applied (2023). DOI: 10.1103/PhysRevApplied.20.044036
