a unit of magnetomotive force; the magnetomotive force produced by a current of 1 ampere passing through one complete turn of a coil. 1 ampere-turn is equivalent to 4π/10 or 1.257 gilberts
Abbreviation: At, A
ampere-turn in American English
(ˈæmpɪrˌtɜrn)
noun
the basic unit of magnetomotive force in the SI system, equal to the force produced by a current of one ampere flowing around one turn of a wire coil (1.257 gilberts): symbol, NI
An ampere-turn is the product of the number of turns in a coil and the current in amperes that flows through it, that was formerly used as the unit of magnetomotive force.
An ampere-turn is represented by a steady, direct electric current of one ampere flowing in a single-turnloop of electrically conducting material in a vacuum.
The magnetomotive force is the force that produces the flux in the magnetic circuit,and the practical unit of magnetomotive force is the ampere-turn.
An ampere-turn is the product of the number of turns in a coil and the current in amperes that flowsthrough it, that was formerly used as the unit of magnetomotive force.
