Solution

Due to the current in the coil P, the Magnetic field will produce in the space near P. Another coil Q is kept in the magnetic field of P that will link magnetic flux.
When the coil P move then flux linkage in the Q will change. This change in flux in coil Q induces emf in it and when the circuit is closed then current will also flow through the coil.
The phenomenon is called electromagnetic induction.
