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. Turns refers to the winding number of an electrical conductor composing an electromagnetic coil. For example, a current of flowing through a coil of 10 turns produces an MMF of . The corresponding physical quantity is , the product of the number of turns, , and the current, ; it has been used in industry, specifically, US-based coil-making industries.

By maintaining the same current and increasing the number of loops or turns of the coil, the strength of the magnetic field increases because each loop or turn of the coil sets up its own magnetic field. The magnetic field unites with the fields of the other loops to produce the field around the entire coil, making the total magnetic field stronger.
