Electrical machines can be found in most of the electrical devices

 Electrical machines can be found in most of the electrical devices we use on a daily basis.  These machines could be in the home, at work, or just out and about.  Find four different electrical machines that you encounter routinely and explain their construction and operation. 

 Electrical machines consist of motors and generators.  The easiest way to explain the difference between the two is that motors use an electrical field to generate a mechanical motion, while generators use mechanical motion to generate an electrical field.
