What is Magnetomotive Force?
When physicists discuss the force of a magnetic field, they refer to it as magnetomotive force (mmf) or magnetic potential. Magnetomotive force is the work that carries a measurable unit of strength through a magnetic circuit. This unit of strength is measured in ampere-turns (AT). Magnetism in a circuit flows from the north to the south pole. Following a specific path, the force of the magnetism is similar to the force in an electrical circuit. While electricity follows a certain path from a point of origin to a receiving point and back, magnetism always flows from one pole to the other. As magnetism flows through the circuit, it produces lines of force, or flux lines, and generates a magnetic field. In simplest terms, anything that produces magnetism can be described as exerting a magnetomotive force. Understanding the basic meaning of the word itself makes it easy to understand its application. Magnetomotive force translates, quite literally, to “magnetic motion causing.” The motion
