Answer:

(b) Increase the number of coils

Step-by-step explanation:

The quantity of induced emf created by increasing the number of individual conductors cutting through the magnetic field is equal to the sum of all the individual loops of the coil, therefore if the coil has 20 turns, there will be 20 times more induced emf than if it only has one.
