The Main Idea
Electric Motors
Our everyday routines heavily rely upon the electric motors in common applications such as refrigerator compressors, water pumps, elevators, clocks, and cars. Electric motors are a common application of the torque that a magnetic field exerts on a current-carrying coil. In order for motors to function the way that they do, the current-carrying coil needs to turn continuously. In order for the current-carrying coil to turn in such a way, you need to make electrical connections to the coil in such a way that just as it is coming to its stable position, you reverse the direction of the current. A simple way to achieve this continuos motion is through a "split-ring commutator" that automatically changes the direction of the current through the coil at just the right moment. Metal tabs make contact between the battery and the commutator, which allows current to flow and for the motor to rotate.
