What Is This Tool?
This converter helps translate magnetomotive force measurements from milliampere turn, a modern SI-based unit, to abampere turn, a unit from the older CGS-EMU system used in electromagnetics.
How to Use This Tool?
-
Enter the magnetomotive force value in milliampere turn [mAt]
-
Select milliampere turn as the input unit and abampere turn as the output unit
-
Click the convert button to obtain the equivalent value in abampere turn [abAt]
-
Interpret the converted values for comparisons or legacy data analysis
Key Features
-
Supports conversion between milliampere turn [mAt] and abampere turn [abAt]
-
Uses a precise conversion factor based on established unit definitions
-
Ideal for electrical engineering and electromagnetic research applications
-
Browser-based and simple to use without needing formulas memorized
Examples
-
10 mAt equals 0.001 abAt by multiplying 10 by 0.0001
-
500 mAt converts to 0.05 abAt using the conversion factor 0.0001
Common Use Cases
-
Specifying excitation levels for small electromagnets and solenoid coils
-
Designing magnetic circuits for inductors and transformers in sensors
-
Converting historical magnetomotive force values from CGS-EMU to SI
-
Supporting academic comparisons between electromagnetic unit systems
Tips & Best Practices
-
Always confirm the input unit to maintain accuracy during conversion
-
Use this tool to translate legacy magnetic circuit calculations for modern applications
-
Be aware that coil turns are dimensionless and integral to the unit definitions
-
Cross-check converted values when analyzing historical or research data
Limitations
-
Abampere turn is rarely used in current measurements and is mostly of historical interest
-
Differences between unit systems might cause minor rounding or scaling inconsistencies
-
Conversion does not account for real-world magnetic losses or coil geometries
-
Users must ensure consistent unit systems to avoid calculation errors
Frequently Asked Questions
-
What does a milliampere turn represent?
-
It represents magnetomotive force as one milliampere of current multiplied by one coil turn, corresponding to 0.001 ampere-turn in SI units.
-
Why convert between milliampere turn and abampere turn?
-
To translate magnetomotive force values between modern SI units and the older CGS-EMU system, facilitating comparisons and interpreting historical data.
-
Is the abampere turn still commonly used today?
-
No, it is largely replaced by the ampere-turn in SI, but remains relevant for historical data and academic study.
Key Terminology
-
Milliampere turn [mAt]
-
A unit of magnetomotive force equaling one milliampere of current multiplied by one coil turn, used in the SI system for magnetic circuits.
-
Abampere turn [abAt]
-
The CGS-EMU unit of magnetomotive force corresponding to one abampere flowing once around a single-turn coil, equal to 10 ampere-turns in SI.
-
Magnetomotive force
-
The quantity of magnetizing force produced by current flowing through a coil, measured in ampere-turns or equivalent units.
