He noticed that he could keep the pendulum moving at a pretty good tick if he triggered the magnetic coil every third pass, so he implemented an Arduino to keep count of passes and apply the ...

Discover the fascinating world of electromagnetic engines with Lego! In this project, we’ll create a unique electric engine using Lego pieces and magnets, replacing traditional gas-powered pistons. By ...

A coil of wire, or solenoid, consists of a wire coiled up into a spiral shape. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet.
