Tesla's Egg Of Columbus-Electromagnetic Eddy Current Experiment

Its lid can be opened to observe the internal structure more comprehensively

Principle: After the motor is powered on, it rotates to drive the two magnets at the top to rotate in the same way. When the magnets rotate to a certain degree, a magnetic eddy current is formed. The metal egg on the wooden disk will rotate with the magnetic eddy current, and with the long axis rotation, the rotation acceleration will eventually form a gyroscopic effect, and the metal egg will stand up.
