A simple homemade electric motor serving no useful purpose apart from cosmetic or educational. Two magnets spin on the armature. One of them triggers a reed switch while the other, in a sequence, gets pulled towards the electromagnet which is a length of enamel insulated magnet wire wrapped around a short roofing bolt. The reed switch momentarily energizes the electromagnet but switches off so that the magnet doesn't stay in place, thus enabling continuous rotation.
