Show Summary Details

Quick Reference


The analogue of electromotive force in a magnetic circuit. Mathematically, it is the circular integral of Hcosθ ds, where Hcosθ is the component of the magnetic field strength in the direction of a path of length ds. The m.m.f. is measured in SI units in ampere-turns. It was formerly called the magnetic potential.
