Magnetic levitation is awesome: From lightbulbs to trains and even hoverboards. This project, however, adds a whole nother level of awesome. Instead of using a static electromagnet, this electromagnet is attached to a CNC-like device with an X, Y, and Z axis. The result: an fascinating method of manipulating physical objects in “zero gravity.” In the video below, the device is used to model planetary orbits.
The device uses a Hall effect sensor to determine the strength of the magnetic field and adjusts an electromagnet accordingly. Furthermore, the entire system uses a projector and webcam to interact with the floating object. For example, it can cast “shadows” as if the levitating object were a light source. Specific project details are unavailable, but electromagnetic levitation is pretty straightforard. Check out the three links below to begin your own levitation project!
