Frequently Asked Questions
-
What is a milliampere-turn (mAt)?
-
A milliampere-turn is a unit of magnetomotive force equal to one milliampere current multiplied by one coil turn, representing a small excitation in magnetic circuits.
-
When should I use kiloampere-turns (kAt)?
-
Kiloampere-turns are used for large magnetomotive forces, such as in the design of heavy electromagnets, electrical machine field windings, and superconducting magnet specifications.
-
How do I convert mAt to kAt?
-
Multiply the milliampere-turn value by 0.000001 to get the equivalent kiloampere-turn value.
