The current in the long, straight wire AB shown in the figure below is upward, and increasing at a rate of di/dt. a) At an instant when the current is i, what are the magnitude and direction of the magnetic field at a distance r to the right of the wire? b) What is the flux dØB through the narrow shaded strip? c) What is the total flux through the loop? d) What is the induced emf in the loop? e) Evaluate the numerical value of the induced emf if a = 12.0 cm, b = 36.0 cm, L = 24.0 cm, and di/dt = 9.6 A/s. %3D HK-dr ka>
