self-induction |
| 释义 |
self-inˈduction Electr.
[self- 3 b.]
The production of an induced current in a circuit by means of a variation in the current of that circuit (see induction 10, inertia 1 b). Also, the coefficient of self-induction.
1865J. C. Maxwell in Phil. Trans. R. Soc. CLV. 472 The equation of the current x in a circuit whose resistance is R, and whose coefficient of self-induction is L, acted on by an external electromotive force ξ, is ξ - Rx = d(Lx)/dt. Ibid. 475 Hence the effect..is to increase the apparent resistance and diminish the apparent self-induction of the circuit. 1873― Electr. & Magn. II. 291 The self-induction of a round wire doubled on itself. 1876Chrystal in Encycl. Brit. VIII. 76/2 What has been called the coefficient of self-induction of a circuit he [Neumann] calls the potential of the circuit on itself. 1886Science 14 May 443/1 The electromotive force of self-induction currents. 1902Encycl. Brit. XXVIII. 56/1 The circuit in the jar C is provided with a sliding piece, F, by means of which the self-induction of the discharging circuit..can be adjusted. 1958Condon & Odishaw Handbk. Physics iv. i. 17/1 If the current in the circuit increases for any reason, the flux through the circuit must also increase, and this gives rise to an emf of self-induction which acts to oppose the increase in the current by Lenz's law.
So self-inˈductive a., produced by self-induction.
1834Faraday Exp. Res. (1844) II. 208 Self-inductive action of a current. 1886Science 14 May 442 The self-inductive capacity of non-magnetic wires of different metals. |
