Magnetomotive Force Converter
How to Use the Magnetomotive Force Converter
Enter a magnetomotive force value, select the source unit and choose the target unit. The converter changes between ampere-turns and gilberts for magnetic-circuit calculations.
Practical Example
A coil carrying 2 A through 100 turns produces 200 ampere-turns of magnetomotive force.
Factors That Affect Magnetomotive Force
MMF is determined by current and number of turns, while resulting magnetic flux also depends on circuit reluctance and material properties.
Frequently Asked Questions
What is an ampere-turn?
It is the magnetomotive force produced by one ampere flowing through one turn.
What is a gilbert?
Gilbert is a CGS unit of magnetomotive force.
Does MMF equal magnetic flux?
No. MMF drives magnetic flux through a magnetic circuit.
Understanding Magnetomotive Force Units
Magnetomotive force drives magnetic flux through a magnetic circuit and is often expressed in ampere-turns, with gilberts appearing in older systems. It depends on current and the number of coil turns.
Converting units changes only the numerical scale. The resulting magnetic flux also depends on circuit reluctance, core material and air gaps, so magnetomotive force alone does not describe the complete magnetic system.
Technical Context and Conversion Notes
Magnetomotive force drives magnetic flux in a magnetic circuit and is commonly expressed in ampere-turns. Coil turns are dimensionless, while the resulting flux also depends on magnetic reluctance.
