Q.

Mutual induction is a process in which current is induced in the neighbouring coil if current flows in a coil. In the figure shown below:

1 Maximum in situation (A)  
2 Maximum in situation (B)  
3 Maximum in situation (C)  
4 Same in all situation  

Ans.

(1)

As both the coils are in the same plane. And induced current is found to be highest when the direction of the coil is at right angle to the magnetic field.
