WebThe magnetomotive force, mmf or f, is analogous to the electromotive force V and may be considered the factor that sets up the flux. The mmf is equivalent to a number of turns of wire carrying an electric current and has units of ampere -turns. If either the current through a coil (as in an electromagnet) or the number of turns of wire in the ... WebThe magnetomotive force is the force that creates the magnetic field.

WebJan 29, 2024 · The below written equations A and B are the main description of terminal characteristic of cumulatively compounded dc generator. The equivalent shunt field current Ieq due to series field and armature reaction is mention here. Ieq=NSE/NF. IA – FAR/NF. So the value of effective shunt field current in generator is given here. In physics, the magnetomotive force (mmf) $${\displaystyle {\mathcal {F}}}$$ is a quantity appearing in the equation for the magnetic flux in a magnetic circuit, Hopkinson's law. It is the property of certain substances or phenomena that give rise to magnetic fields: See more The SI unit of mmf is the ampere, the same as the unit of current (analogously the units of emf and voltage are both the volt). Informally, and frequently, this unit is stated as the ampere-turn to avoid confusion with … See more The term magnetomotive force was coined by Henry Augustus Rowland in 1880. Rowland intended this to indicate a direct analogy with See more Cited sources • Hon, Giora; Goldstein, Bernard R, "Symmetry and asymmetry in electrodynamics from Rowland to Einstein", Studies in History and Philosophy of Modern Physics, vol. 37, iss. 4, pp. 635–660, Elsevier … See more WebMagnetomotive Force ( m.m.f ) - Important Terms [Hindi] Magnetomotive force.
