Magnetic levitation - Simulated levitation where the floater has full freedom - with plots

Magnetic levitation - Simulated levitation at a rotor frequency of 300 Hz where the floater has full rotational and translational freedom. The rotor is displaced by 1.2 mm relative to the rotation axis, yielding a slight vertical B-field, the effective damping is 1 Pa*s, both magnetisations are T and the diameters are 12.7 mm and 19 mm for floater and rotor respectively. The top-left figure, phi, shows the phase angle, which is the angle between the projection onto the xy-plane of the respective magnetization vectors of the rotor and floater magnets. The top-right figure shows the floater polar angle, theta. The lower-left figure shows the vertical floater/rotor distance. The lower-right figure shows the xy-position of the floater with origin on the rotors rotation axis. On the right, the blue/red sphere is the rotor magnet, the green/orange is the floater magnet and yellow arrows represent magnetic moments. Positions and sizes are to-scale.
