About the magnetomotive force converter

Magnetomotive force (MMF) is the magnetic analog of voltage — it drives magnetic flux around a magnetic circuit. The SI unit is the ampere-turn (At), the product of current in a coil and the number of turns: a 5-turn coil carrying 2 A produces 10 At. The CGS unit is the gilbert (Gb), where 1 At ≈ 1.257 Gb. Engineers designing solenoids, transformers, and electromagnets work in ampere-turns to size cores and windings.

Frequently asked questions

  • How do you calculate ampere-turns?

    Multiply the current through the coil by the number of turns: MMF = N × I. A 100-turn coil at 0.5 A produces 50 At.

  • What is the gilbert?

    The CGS-emu unit of MMF. 1 At ≈ 1.2566 Gb (the conversion factor is 4π/10).
