What Is This Tool?
This unit converter helps you translate magnetomotive force values from abampere turn (abAt), a CGS-EMU unit, to milliampere turn (mAt), a finer-scaled SI-compatible unit. It is useful for analyzing magnetic circuits, converting legacy data, and designing low-current electromagnetic devices.
How to Use This Tool?
-
Enter the numerical value in abampere turn (abAt) you wish to convert
-
Select the source unit as abampere turn [abAt]
-
Choose the target unit milliampere turn [mAt]
-
Perform the conversion to get the equivalent value in milliampere turn

Common Use Cases
-
Translating historical magnetomotive force data from CGS-EMU to SI units for analysis
-
Designing magnetic circuits in sensors and actuators requiring precise current×turn measurements
-
Teaching differences between electromagnetic unit systems in academic courses
-
Specifying coil excitation values in low-current electronic devices such as relays
Tips & Best Practices
-
Ensure consistent interpretation of coil turns and current when converting units
-
Use milliampere turn units for low-current magnetomotive force specifications
-
For large magnetomotive force values, consider converting to ampere-turn units for clarity
-
Leverage this conversion to reconcile legacy data with modern SI unit standards
Limitations
-
The abampere turn is mostly replaced by the SI ampere-turn unit in current practice
-
Conversion accuracy relies on consistent coil and current definitions
-
Milliampere turn units are less practical for very high magnetomotive force levels
Frequently Asked Questions
-
What does one abampere turn represent?
-
One abampere turn (abAt) is the CGS-EMU unit of magnetomotive force produced by a current of one abampere passing once around a single turn of coil.
-
How do I convert abampere turn to milliampere turn?
-
Multiply the value in abampere turn by 10,000 to obtain the equivalent in milliampere turn.
-
Why use milliampere turn units instead of abampere turn?
-
Milliampere turn units provide a finely scaled SI-compatible unit better suited for specifying low-current magnetomotive forces in modern magnetic circuit design and sensors.
Key Terminology
-
Abampere turn [abAt]
-
A CGS-EMU electromagnetic unit of magnetomotive force equal to one abampere flowing once around a single-turn coil.
-
Milliampere turn [mAt]
-
A magnetomotive force unit equal to one milliampere multiplied by one coil turn; used for low-current magnetic circuit specifications.
-
Magnetomotive force (MMF)
-
The product of current and coil turns that produces the magnetizing force in a magnetic circuit.
