Physics current demonstration model, Columbus egg-shaped AC Tesla, coil rotating magnetic field
About this item
The Columbus egg is one of the signature products of Nikola Tesla - the father of communication. AC current passes through the circuit, creating a rotational magnetic field. This allows the center metal object to be rotated
Based on the original, we adopted a capacitive time sharing circuit, lowering the volume and transparent structure, so everyone can see the internal structure and principles
Plug the power cord into the product and turn the switch. Not recommended to use every 5 minutes or more. Coil will get hot. We recommend you stop it for a while and turn it on again
Columbus egg model can be used as education, technical decoration, experimental educational display rack, etc. It is very suitable for children gifts and education with students, which can effectively increase their interest in learning
Design Principle
In order for the Columbus Egg to work, there must be two-phase AC with a phase difference of 90 degrees. So we used the method of single-phase induction motor, that is, capacitor phase separation, using the capacitor voltage to lag the current by 90 degrees. We solved the problem of the power supply of the Columbus Egg.
The Columbus Egg is an egg-shaped copper block. In a rotating magnetic field, the egg rotates on its long axis and eventually stands up due to the gyroscopic effect.
