29.7 The current in the long, straight wire *AB* shown in Fig. E29.7 is upward and is increasing steadily at a rate *di/dt*.

(a) At an instant when the current is *i*, what are the magnitude and direction of the field ** B** at a distance

(b) What is the magnetic flux 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* = 9.60 A/s.
