The ampere-turn (symbol A⋅t) is the MKS (metre–kilogram–second) unit of magnetomotive force (MMF), represented by a direct current of one ampere flowing in a single-turn loop. [1] Turns refers to the winding number of an electrical conductor composing an electromagnetic coil .
Structure of a coil with an even number of turns per. Given: Wire-Ø Cu 0,3 mm → CU1L=0,334 mm (According to the table) Coil width: should be 9 mm // 150 turns, coil inner diameter 8mm. a) Calculation of the winding width In the first iteration step, a winding with the same number of windings per layer is assumed or taken as a basis.
The rotating magnetic field is the key principle in the operation of induction machines.The induction motor consists of a stator and rotor.In the stator a group of fixed windings are so arranged that a two phase current, for example, produces a magnetic field which rotates at an angular velocity determined by the frequency of the alternating current.
The armature windings interact with the magnetic field (magnetic flux) in the air-gap; the magnetic field is generated either by permanent magnets, or electromagnets formed by a conducting coil. The armature must carry current , so it is always a conductor or a conductive coil, oriented normal to both the field and to the direction of motion ...
A bifilar coil is an electromagnetic coil that contains two closely spaced, parallel windings. In electrical engineering , the word bifilar describes wire which is made of two filaments or strands.
Mean Length Turn, sometimes Mean Length per Turn is the mean length of winding turn in a coil, usually referred to by the initials MLT. The dimensions of a coil former or bobbin define the MLT of a full wound coil. [ 1 ]

Furthermore, in a thought experiment with a coil of turns, where each turn forms a loop with exactly the same boundary, each turn will "link" the "same" (identically, not merely the same quantity) flux, all for a total flux linkage of =. The distinction relies heavily on intuition, and the term "flux linkage" is used mainly in engineering ...
