Limitations
-
Gilbert is a non-SI unit from the CGS system and requires careful conversion to avoid unit confusion.
-
Rounding in the approximate conversion value between gilberts and ampere-turns can affect precision.
-
Not suitable for applications requiring extremely high numerical accuracy due to unit system differences.
Frequently Asked Questions
-
What does milliampere turn represent in magnetic circuits?
-
Milliampere turn is a unit of magnetomotive force equal to one milliampere of current multiplied by one coil turn, used to quantify the product of current and turns generating magnetic force.
-
Why convert milliampere turn to gilbert units?
-
Converting helps translate magnetomotive force values between modern SI units and the older CGS-EMU system for comparison and analysis of legacy data and standards.
-
Is the gilbert unit part of the International System of Units (SI)?
-
No, the gilbert is a CGS-EMU unit and not officially part of the SI system, so conversions are needed when working across unit standards.
Key Terminology
-
Milliampere turn (mAt)
-
A unit of magnetomotive force equal to one milliampere of current multiplied by one turn of a coil, representing the excitation in SI terms.
-
Gilbert (Gi)
-
The CGS-EMU unit of magnetomotive force defined as 10 divided by (4π) ampere-turns, used in legacy magnetic circuit analysis.
-
Magnetomotive Force (MMF)
-
A quantity representing the magnetic potential or driving force produced by electric current flowing in coil turns.
