Figure 10.1 Figure 10.1 An example illustrating the application of Faraday’s law to the case of a constant magnetic flux density B and a moving path. The Shorting bar moves to the right with a velocity v, and the circuit is completed through the two rails and an extremely small high-resistance voltmeter. The voltmeter reading is V12 = -Bvd.

Figure 10.2 Figure 10.2 An apparent increase in flux linkages does not lead to an induced voltage when one part of a circuit is simply substituted for another by opening the switch. No indication will be observed on the voltmeter.

Figure 10.3 Figure 10.3 An filamentary conductor forms a loop connecting the two plates of a parallel-plate capacitor. A time-varying magnetic field inside the closed path produces an emf of V0 cos ωt around the closed path. The conduction current I is equal to the displacement current between the capacitor plates.
