Tesla's Egg of Columbus
A,copper ellipsoid egg(PhiTOP) mysteriouslyspins and stands uprightin this modern version ofTesla's famousdemonstration from the1893 World's Fair inChicago that first showcased the principlesbehind wireless powertransfer and hisAC induction motor.
Rotating magnetic fields from under the wooden platform induce electric eddy currents to flow in the copper PhiTOP- these currents then create their own magnetic field which oppose the initial fields underneath and pushes the PhiTOP to spin.
This version differs from Tesla’s in that the rotating magnetic fields are created by, well, a pair of rotating neodymium magnets (revealed by lifting the top platform in this model).
Credit to astrophysicist Kenneth Brecher, the creator of the PhiTOP, and this unique means of using a common lab magnetic stirrer to create the induced currents. Finally, the ellipsoid top stands up vertically (when spun with sufficient rotational velocity) due to physics similar to that of the tippe-top.
