Magnetic flux and induced emf

A coil with 1500 turns, a radius of 5.0 cm and a resistance of 12Ω surrounds a solenoid with 250 turns/cm and a radius of 4 cm; see figure. The current in the solenoid changes at a constant rate from 0 to 20 A in 0.10 s. The magnitude of the induced current (in A) in the 1500 turn coil is ( Take π2=10,  Neglect self inductance of the coil)
