Soft Iron Core

Moving-coil meter. A moving-coil meter is a very common form of analog voltmeter because of its sensitivity, accuracy, and linear scale, although it only responds to DC signals. As shown schematically in Fig. 10.3, it consists of a rectangular coil wound round a soft iron core that is suspended in the field of a permanent magnet.
