From The Collaborative International Dictionary of English v.0.48 [gcide]:

  ampere-turn \ampere-turn\, Ampere turn \Amp[`e]re turn\ (Elec.)
     A unit of magnetomotive force equal to the product of one
     complete convolution (of a coiled conductor) into one
     amp[`e]re of current; thus, a conductor having five
     convolutions and carrying a current of half an amp[`e]re is
     said to have 21/2 amp[`e]re turns. The magnetizing effect of


     a coil is proportional to the number of its amp[`e]re turns.
     [Webster 1913 Suppl.]
