The Active Magnetic Levitation laboratory test-rig was extended by the magnetic field sensor to perform measurements in the space between electromagnet and the levitating sphere. The data fusion of displacement, magnetic flux and coil current sensors was used to study dependencies during the object’s start-up, stable levitation and under oscillations. The non-linear and surjective characteristics of the magnetic inductance versus object displacement and versus coil current was obtained. The experimental data is illustrated by time domain diagrams. The analysed data and obtained characteristics are presented.
