AVT2741 / 1 A

Magnetic levitation relies on the floating of a metal object in the air. This is possible thanks to the magnetic field invisible to the human eye. One of the most important elements of a device that demonstrates this type of phenomenon is a system that allows to keep the levitating body in a specific, fixed position. In AVT 2741/1 , laser light creates a barrier partially obscured by a levitating object. The remaining part of the beam reaches the photoelement, in which an electrical signal is generated proportional to the intensity of light. As a result of its reinforcement and appropriate shape, information about the location of the object is obtained. It directly affects the operation of the electromagnet controller.

The device is especially recommended for fans of physics and unusual phenomena
