Frequently Asked Questions
-
What does kiloampere-turn measure?
-
A kiloampere-turn (kAt) measures magnetomotive force as the product of coil current and the number of turns, equal to 1,000 ampere-turns.
-
Why convert kiloampere-turns to milliampere-turns?
-
Converting to milliampere-turns allows expressing magnetomotive force at a smaller scale, useful for low-current precision designs in sensors and actuators.
-
Is the conversion affected by magnetic materials?
-
No, the conversion is purely linear and does not account for magnetic material properties or thermal effects influencing the actual magnetomotive force.
Key Terminology
-
kiloampere turn [kAt]
-
A magnetomotive force unit equal to 1,000 ampere-turns, representing coil current multiplied by the number of turns.
-
milliampere turn [mAt]
-
A magnetomotive force unit equal to one milliampere of current times one coil turn, representing 0.001 ampere-turns.
-
Magnetomotive Force (MMF)
-
The driving quantity that produces magnetic flux in a magnetic circuit, calculated as current multiplied by coil turns.
