Design Intention: Tesla's Egg of Columbus is one of the representative products of Nikola Tesla, the father of alternating current. The alternating current passes through the circuit and generates a rotating magnetic field, which makes the metal object in the center rotate. It is very magical. On the basis, this product uses a capacitive time-sharing circuit, which reduces the size, and uses a transparent structure, which can intuitively and clearly see the internal structure and principle.
Technical Points: Customized silicon steel core, 3D printed winding skeleton, transparent acrylic structure, fine winding group, 35mm solid aluminum ball.
Usage: Plug the power cord into the product and turn it by turning the switch. It is not recommended to use it for more than 5 minutes each time. The coil will heat up. It is best to stop it for a period of time and then turn it on again.
Note: The product can not be changed the power supply voltage and power without permission; it is strictly forbidden to connect the wires privately; acrylic is easy to deform, crack, wear, and will be shipped with a film, please do not drop it or put it in a high temperature environment; Rotate the motor to avoid danger.
Significance and Value: Columbus eggs can be used as educational toys, technological ornaments, experimental teaching displays, etc.; used to display and explain the principles of rotating magnetic field models and asynchronous motors. Strengthen scientific quality training.

Made a few modifications, ie: a power switch and fan with a veneer top on the upper layer.
It works well with copper eggs and orbs as well.

Revie of Columbus' Egg Device
The device seems to work well, although it does not move heavier objects (larger steel spheres, etc.). Mine did not come with a phi top, but it did come with a sphere (aluminum?). I already had two phi tops. The light one spins and lifts, but the brass one only spins. Does this device do anything else, by the way?
