Construct a simple little electric motor for a clear understanding of how the technology works. All the main components to create a working DC motor are included such as the armature, commutator, field poles, etc. When current is applied to the coil in the electromagnetic field the coil will turn. The magnetic field can be produced with either the supplied ferrite magnet or the electromagnet. Everything can be mounted onto the supplied plastic enclosure. • Assembly time: 30 minutes • Recommended for ages 8+ • Requires 3VDC-6VDC power source • Dimensions: 132(L) x 104(W) x 90(H)mm
