Magnetic levitation of an iron ball
The mechanism of magnetic levitation of an iron ball in a plastic box [S. Sasaki, I. Yagi, and M. Murakami, J. Appl. Phys. 95, 2090 (2004)]. was investigated quantitatively using measurement of the magnetic moment of the iron ball and ring magnet used in the levitation experiment. This phenomenon is very interesting not only as a physical ...
