Magnetomotive Force Unit Definitions

Ampere-turn (A·t)
SI unit of MMF. A coil with 100 turns carrying 2 A has 200 A·t.
Gilbert (Gb)
CGS unit = 10/(4π) A·t ≈ 0.79577 A·t.

Frequently Asked Questions

What is magnetomotive force used for?

MMF determines how much magnetic flux a coil creates in a magnetic circuit, used in transformer and motor design.
