In Fig (a) and (b), two air-cored solenoids P and Q have been shows. They are placed near each other. In Fig (a), when IP, the current in P, changes at the rate of 5 A/s, an emf of 2 mV is induced in Q. The current in P is then switched off, and the current changing at 2 A/sis fed through Q as shows in the figure. What emf will be induced in P?
