Building Totally Silent Levitating Fan Using Lego


Let’s level up our levitating Lego concept by building a totally silent motor that floats on a cushion of magnets!

This Lego build makes use of a reed switch to detect magnetic fields, which then sends pulses to a wire coil that powers the rotation of the levitating fan.Watch the video from Jamie’s Lego Jams:

It’s quite mesmerising watching this desktop contraption float in place, while spinning wirelessly.


Because of how simple this circuit is, you can easily build your own motors using this principle. All you need is some wire, a reed switch, and a power source, like some batteries! I hope this helps inspire some Lego builders out there to experiment more with what it can do.
