Unformatted text preview: assembly. A motor essentially uses the idea of magnetism to work. The fundamental law of magnetism states that likes repel and opposites attract. A basic motor contains the following six parts: an armature, a communicator, brushes, an axle, a field magnet, and a power source. The armature acts as an electromagnet or a magnetic field by coiling wire around two or more poles of a metal core. One side of it will be positive while the other is negative. It has an axle where a communicator is also attached. The communicator and brushes are used to switch the magnetic field of the armature around. The point of that is to create a continuous attracting and repelling force from the field magnet, a fixed magnet with a positive end and a negative end, to the armature, which therefore continuously spins the armature around its axle....
