autoinductionn.

Brit.

/ˌɔːtəʊɪnˈdʌkʃn/, U.S.

/ˌɔdoʊənˈdəkʃ(ə)n/,

/ˌɑdoʊənˈdəkʃ(ə)n/

Origin: Formed within English, by compounding; perhaps modelled on a French lexical item. Etymons: auto- comb. form¹, induction n.

Etymology: < auto- comb. form¹ + induction n., perhaps after French auto-induction (1883 or earlier in sense 1). Compare earlier self-induction n.

1. = self-induction n. 2 Now rare.

1885 Telegr. Jrnl. & Electr. Rev. 29 Aug. 204/2 If you would permit me a little space in your next issue, I would point out the theory, which I entertain, of the operation of an earth wire in an ‘auto induction cable’.

1911 Jrnl. Inst. Electr. Engineers 47 516 The effective speed of transmission on this line is far below the theoretical speed of transmission... This difference appears to be due..also to the influence of the auto-induction of the line.

1921 G. M. MacKee X-rays & Radium Treatm. Dis. Skin iii. 67 The autotransformer controls the current in the primary circuit by the impedance of autoinduction.

1991 Ultrasonics Internat. 91 365 In the case of the D sample the value of the autoinduction coefficient is CA = 0.08.

2. Biology and Medicine. The induction (in various senses) of something by itself or without external stimuli. In later use: (Pharmacology) the induction by a substance (esp. a drug) of enzymes responsible for its own degradation. Cf. autoinducer n.

1961 Jrnl. Surg. Res. 1 139/1 When dead muscle serving as the inductor and the young connective tissue cells being induced originate in the same individual, the process must be one of autoinduction.

1970 Jrnl. Bacteriol. 104 313/2 Since the phenomenon occurs without external intervention, it must be attributed to a conditioning of the medium effected by the growing cells. We have referred to the phenomenon as ‘autoinduction’.

1972 Biochem. Pharmacol. 21 450 There was a faster plasma clearance of the drug, probably due to autoinduction.

2006 D. P. Moore Little Black Bk. Psychiatry (ed. 3) vi. 193 Carbamazepine induces its own metabolizing enzymes over ~21 d, and with this autoinduction, the half-life falls dramatically and dose increases are generally required.
