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 Aluminium egg. .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. .For Age: 8+
