COUPLING COEFFICIENT QR Code Decoder In None Using Barcode Control SDK for Software Control to generate, create, read, scan barcode image in Software applications. Making Denso QR Bar Code In None Using Barcode drawer for Software Control to generate, create QR Code image in Software applications. A coil containing N turns with magnetic ux linking each turn has total magnetic ux linkage N. By Faraday s law, the induced emf (voltage) in the coil is e d=dt N d=dt . A negative sign is frequently included in this equation to signal that the voltage polarity is established according to Lenz s law. By de nition of selfinductance this voltage is also given by L di=dt ; hence, L di d N dt dt or L N d di 5a Scanning Quick Response Code In None Using Barcode decoder for Software Control to read, scan read, scan image in Software applications.

If all of the ux links the coils without any leakage ux, then k 1. On the other extreme, the coil axes may be oriented such that no ux from one can induce a voltage in the other, which results in k 0. The term close coupling is used to describe the case where most of the ux links the coils, either by way of a magnetic core to contain the ux or by interleaving the turns of the coils directly over one another. Coils placed sidebyside without a core are loosely coupled and have correspondingly low values of k.

This arrangement results in close coupling, which was mentioned in Section 14.2. To determine the proper signs on the voltages of mutual inductance, apply the righthand rule to each coil: If the ngers wrap CHAP. 14] MUTUAL INDUCTANCE AND TRANSFORMERS
Fig. 144 around in the direction of the assumed current, the thumb points in the direction of the ux. Resulting positive directions for 1 and 2 are shown on the gure. If uxes 1 and 2 aid one another, then the signs on the voltages of mutual inductance are the same as the signs on the voltages of selfinductance. Thus, the plus sign would be written in all four equations (2) and (3). In Fig. 144, 1 and 2 oppose each other; consequently, the equations (2) and (3) would be written with the minus sign. Natural Current Further understanding of coupled coils is achieved from consideration of a passive second loop as shown in Fig. 145. Source v1 drives a current i1 , with a corresponding ux 1 as shown. Now Lenz s law implies that the polarity of the induced voltage in the second circuit is such that if the circuit is completed, a current will pass through the second coil in such a direction as to create a ux opposing the main ux established by i1 . That is, when the switch is closed in Fig. 145, ux 2 will have the direction shown. The righthand rule, with the thumb pointing in the direction of 2 , provides the direction of the natural current i2 . The induced voltage is the driving voltage for the second circuit, as suggested in Fig. 146; this voltage is present whether or not the circuit is closed. When the switch is closed, current i2 is established, with a positive direction as shown. Fig. 145 EXAMPLE 14.2 Suppose the switch in the passive loop to be closed at an instant t 0 when i1 0. the sequence of the passive loop is (see Fig. 146). di2 di M 1 0 dt dt For t > 0,
