Introduction to Magnetomotive Force (MMF)

The magnetomotive force (MMF) in a magnetic circuit is analogous to electromotive force (EMF) in an electrical circuit. It represents the potential for creating magnetic flux in a material with a given reluctance due to the flow of current through a coil. In this formula, MMF represents the magnetomotive force, I is the current flowing through the coil, and Φ is the magnetic flux.

Parameter usage:


Data validation

The current should be greater than or equal to zero. The reluctance should be greater than zero.


This formula helps calculate the magnetomotive force in a magnetic circuit based on the current flowing through the coil and the reluctance of the material.
