Abstract

Experimental study on the dynamic behaviour of magnetic levitating magnet-magnetic fluid element in the external alternating magnetic field is described. Two types of element motions occur according to the magnetic field strength and frequency of the external alternating magnetic field. Seesaw motions of the element and harmonic motions of magnetic fluid surface are observed using high-speed video camera system. Transient phenomena in element response and the change of spikes pattern on the magnetic fluid surface are revealed.
