**Formula:**`MMF = I × Φ`

## 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,

**is the current flowing through the coil, and Φ is the magnetic flux.**

*I*## Parameter usage:

`current`

= current flowing through the coil`reluctance`

= reluctance of the material

## Output:

`MMF`

= magnetomotive force

## Data validation

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

## Summary

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.
