ELECTRIC MOTORS 101: Understanding the Basics of Electric Motor Technology An Overview
... Stranded wire, used in some of GM’s induction motors, is composed of a bundle of round wires to make a large conductor. Stranded wire is more flexible than solid wire, making it more pliable and easy to work with. Bar wound wire, used in GM’s permanent magnet motors, is a solid piece of wire bent in ...

... We saw in Chapter 19 that moving charges (currents) create magnetic fields. Nature often reveals a great deal of symmetry. So, scientists wondered, “Can magnetic fields can create currents?” You might guess that the answer is, “Yes.” In this chapter, we’ll explore this physical process known as indu ...

History of electromagnetic theory
For a chronological guide to this subject, see Timeline of electromagnetic theory.The history of electromagnetic theory begins with ancient measures to deal with atmospheric electricity, in particular lightning. People then had little understanding of electricity, and were unable to scientifically explain the phenomena. In the 19th century there was a unification of the history of electric theory with the history of magnetic theory. It became clear that electricity should be treated jointly with magnetism, because wherever electricity is in motion, magnetism is also present. Magnetism was not fully explained until the idea of magnetic induction was developed. Electricity was not fully explained until the idea of electric charge was developed.
