DC Motors starts by clearly and concisely introducing students to the link between electricity and magnetism and how the two can combine to produce movement. The principles of the electric motor, how useful motion can be achieved, leading to the design for a basic DC motor are carefully explained, followed by improvements to the design that lead to the production of a practical working motor. Key 3D animations provide clear, visual explanations of the inner workings of DC motors and add to the outstanding clarity and understanding that this program brings to the topic.
