Applications of Permanent Maglev Bearing in Heart Pumps and Turbine Machine
Figure 4
Illustration of Gyroeffect. (a) a gyro can rotate on top of the hemisphere if its rotating speed is large enough, but will go down if it is in standstill or rotates not fast. The toy Levitron (b) has same property: the small magnetic ring can rotate above the large ring if the small ring has enough speed, but will fall off if its speed decreases to certain value [6].
