UnitConMagnetomotive Force
Magnetomotive force, or MMF, drives magnetic flux through a magnetic circuit. It is analogous to electromotive force in electrical circuits and is commonly expressed in ampere-turns. This converter helps compare SI and CGS magnetic-circuit units. It is useful in transformer, solenoid, and electromagnet design.

Frequently asked questions
Magnetomotive force is the quantity that drives magnetic flux through a magnetic path. It is usually produced by current flowing through coil turns.
More MMF generally drives more flux, though the magnetic material and path geometry also matter. The relationship is similar in spirit to voltage and current in circuits.
The gilbert is a CGS unit of magnetomotive force. Ampere-turn is the more common unit in SI-based engineering work.
