An air cored solenoid with length 30 cm, area of cross-section 25 cm^2 and number of turns 500 carries a current of 2.5 A. The current is suddenly switched OFF in a brief time of 10^(-3) s. How much is the average back emf induced across the ends of the open switch in the circuit? (Ignore the variation in magnetic field near the ends of the solenoid)
