inducedadj.
/ɪnˈdjuːst/ 1.
a. Brought on, caused, or produced, by attraction, persuasion, etc. (see esp. induce v. 4b); induced current, an electric current excited by induction n. (sense 10). Also, affected by induction as induced magnet. More widely (in induce v. 4), caused or brought into being artificially or by some extraneous agent or process; not spontaneous (cf. induction n. 9).

1904 F. Soddy Radio-activity ii. 33 With the power of a radio-active element to produce a radio-active emanation is bound up its power to impart radio-activity to objects in the neighbourhood. Rutherford discovered this property for the thorium emanation, and designated it the excited activity. M. and Mme. Curie..called it the induced activity.

1926 H. Glauert Elem. Aerofoil & Airscrew Theory x. 132 The lift force is..inclined backwards at the small angle..and therefore gives a component in the direction of the drag force. This component is called the induced drag, since it is caused by the induced velocity of the trailing vortices.
1931 Flight 1 May 384/2 And how little headway have made such conceptions as induced drag, profile drag and span loading.
1948 Sci. News 7 25 For an aerofoil it is necessary to introduce also the induced drag, i.e. the part of the total resistance which depends entirely on the lift.
1962 F. I. Ordway et al. Basic Astronautics viii. 340 There are three basic types of aerodynamics drag: skin-friction drag, form drag, and induced drag.
