Answer question numbers (a)-(d) on the basis of your understanding of the following paragraph and the related studied concepts :
The phenomenon of electromagnetic induction is the production of induced current in a coil placed in a region where the magnetic field changes with time. The magnetic field may change due to a relative motion between the coil and a magnet placed near to the coil. If the coil is placed near to a current carrying conductor, the magnetic field may change either due to a change in the current through the conductor or due to the relative motion between the coil and conductor. The direction of the induced current is given by the Fleming's right-hand rule.
What is the cause of current induced in a coil in electromagnetic induction phenomenon ?
