A circular wire loop (radius r, resistance R) encloses a region of uniform magnetic field, B, perpendicular to its plane. The field (occupying the shaded region in Fig. 7.56) increases linearly with time (B = αt). An ideal voltmeter (infinite internal resistance) is connected between points P and Q.
