    "abstract": "In this paper we analyze the spinning motion of the hovering magnetic top. We\nhave observed that its motion looks different from that of a classical top. A\nclassical top rotates about its own axis which precesses around a vertical\nfixed external axis. The hovering magnetic top, on the other hand, has its axis\nslightly tilted and moves rigidly as a whole about the vertical axis. We call\nthis motion synchronous, because in a stroboscopic experiment we see that a\npoint at the rim of the top moves synchronously with the top axis. We show that\nthe synchronous motion may be attributed to a small deviation of the magnetic\nmoment from the symmetry axis of the top. We calculate the minimum angular\nvelocity required for stability in terms of the moments of inertia and magnetic\nfield and show that it is different from that of a classical top. We also give\nexperimental results that were taken with a top whose moment of inertia can be\nchanged. These results show very good agreement with our calculations.",
